This exciting model teaches the Light Reactions and Calvin Cycle in photosynthesis! It also explains the cyclic photophosphorylation and can be used to compare with our amazing ATP Synthase 3D model.


Photosynthesis is the process by which green plants, algae and some bacteria turn sunlight into energy-rich molecules like carbohydrates and oxygen. This is the reason that the Earth is blanketed with an oxygen-rich atmosphere, and it’s the source of most of our food and energy.

Photosynthesis occurs in regions of the cell called chloroplasts. Pigment molecules, including the green one that gives plant leaves their color (chlorophyll), absorb light energy to power two main stages of the reaction.

The light reactions of photosynthesis occur in the thylakoid membranes, and the dark reactions (also known as the Calvin cycle) occur in a region of the chloroplast stroma that contains enzymes to “fix” carbon dioxide from water into carbohydrates. Both the light and dark reactions are driven by energy from absorbed sunlight (an exergonic reaction). They produce the chemical energy-rich molecule ATP, which is used to power cellular respiration.

Light Reactions

The light reactions of photosynthesis take place in the thylakoid membranes of organelles called chloroplasts. They convert solar energy into adenosine triphosphate (ATP) and reduced electron carrier nicotinamide adenine dinucleotide phosphate (NADPH). The light reactions depend on large complexes of proteins and pigments that are optimized to absorb specific wavelengths of light, known as photosystems. There are two types of photosystems, PSI and PSII, both embedded in the thylakoid plasma membrane.

Each photosystem contains a special pair of chlorophyll a molecules called the reaction center. These molecules act as energy funnels, passing energy to other pigments through direct electromagnetic interactions known as resonance energy transfer. The excited pigments then pass the energy to the central region of the photosystem where it is used to generate ATP and NADPH.

Electron Transport

The final stage of photosynthesis involves a series of reactions that uses energy from sunlight to produce glucose and oxygen. The plant then releases the oxygen into the atmosphere, where it can be used by humans and animals to breathe.

These reactions are called the electron transport chain. They are a series of redox reactions that work together like a bucket brigade, passing electrons rapidly from one protein complex to the next. At the end of the chain, electrons are reduced to molecular oxygen by enzymes such as ATP synthase.

Electron carriers are small organic molecules that shuttle electrons between the two compartments where the light-dependent reactions and the carbon dioxide fixation occur. The 3D images reveal that these carriers have channels that connect the thylakoids to the pyrenoid.


This part of photosynthesis generates ATP by adding a phosphate group to ADP. It is powered by the energy of light that strikes the photosynthetic reaction centers.

Electrons from water or a different electron donor are removed from the ETC and donated to the carrier, which is then accepted by NADP+ (generating an oxidation-reduction cycle). This generates a proton gradient across the thylakoid membrane and drives ATP synthesis.

Anoxygenic photophosphorylation can occur with oxygen or without it, but in either case it involves a noncyclic electron transport chain. Oxygenic photophosphorylation is used by cyanobacteria and algae, where the waste product is O2. Anoxygenic photophosphorylation is used by green bacteria and some plants. In the latter, it can involve diverse electron donors other than water or succinate and the waste product is never O2. Plants can switch between cyclic and noncyclic photophosphorylation to achieve the right ratio of ATPs to NADPH needed for carbon assimilation in their dark phase.

ATP Synthesis

The chemiosmotic proton gradient drives ATP synthase to combine ADP and inorganic phosphate (Pi) into adenosine triphosphate (ATP). This molecular motor complex consists of two molecular machines – the membrane-bound Fo complex and the soluble F1 complex – linked by a central stalk. The F1 complex is prevented from rotating by binding to a protein called the Stator.

The energy released by ATP synthesis is converted to a thermal free energy that can be dissipated as waste heat. Thus, a tradeoff exists between the speed of ATP synthesis and its efficiency.

The central stalk gamma subunit rotates 120o counterclockwise with each ATP synthesis or hydrolysis step. This rotation is coupled to the protonation-deprotonation cycles of three c subunits. These steps lead to the transition from state 1 to state 10, and the whole sequence is reversible.

Photosynthesis: Capturing Sunlight to Make Sugar and Oxygen

A Photosynthesis Equation Explained

Photosynthesis is a process by which plants and some bacteria convert carbon dioxide, water, and energy from light into sugar (glucose) and oxygen. The first step, known as the light reactions or photochemical reactions, energizes electrons and creates a proton gradient.

These reactions require the green pigment CHLOROPHYLL, which likes to absorb blue, violet, orange, and red frequencies of light and tends to reflect yellows and greens.

The Reactants

Six molecules of carbon dioxide and six molecules of water react with light energy to produce one molecule of glucose and six molecules of oxygen. This balanced chemical equation, known as the photosynthesis equation, illustrates the overall process of how plants and some bacteria produce sugar from carbon dioxide and water.

This reaction, called photosynthesis, gives plants the energy they need to live. It also removes carbon dioxide from the atmosphere and replaces it with life-sustaining oxygen.

Photosynthesis is a two-stage process, with the first stage referred to as the “light reactions” and the second phase being called the Calvin cycle. During the light reactions, thylakoid membranes in chloroplasts convert light energy into adenosine triphosphate (ATP) and NADPH.

All chemical reactions must be balanced, so there must be equal numbers of atoms on the reactant side and the products side. This is how the photosynthesis equation demonstrates the law of conservation of mass. In this video we’ll take a closer look at the reactants and products in this important biological reaction.

The Products

The products of photosynthesis are a sugar molecule called glucose and oxygen gas. Glucose is used to provide energy for plant cells and is also a raw material in the formation of organic compounds such as cellulose, amino acids, proteins, lipids and other biomolecules.

The balanced equation for photosynthesis shows that six molecules of carbon dioxide and twelve molecules of water are converted by sunlight and chlorophyll into one molecule of glucose and six molecules of oxygen. In addition, the energy of sunlight is transferred to a high-energy molecule called ATP that provides the chemical energy needed to drive all other biochemical reactions of the photosynthesis process.

Photosynthesis is essential for plants, algae and species of bacteria that produce their own food. It is also helpful for the animal species that rely on plants and other photosynthetic organisms for their food supply. Oxygen released as a bi product of photosynthesis is necessary for all animals to carry out cellular respiration.

The Process

Plants (and algae, cyanobacteria, and some bacteria) use sunlight to create food. This process is called photosynthesis, & it turns carbon dioxide & water into glucose & oxygen. It also produces adenosine triphosphate (ATP).

The synthesis of glucose is divided into two steps: the light reactions & the dark reactions. The light reactions are also called the photosynthetic or photochemical reactions, & they occur in structures inside the plant cell called chloroplasts.

Light energy is absorbed by green pigments called chlorophyll a & chlorophyll b. These molecules absorb blue, violet, orange, & red wavelengths of light, & reflect yellow & green wavelengths. This explains why plants look so green!

The absorbing of light energy by these molecules energizes electrons, which are then shuttled through an electron transport chain. This process generates a proton gradient across the thylakoid membrane. The energy from this gradient is used to form ATP from ADP & inorganic phosphate. This ATP is then used to reduce carbon dioxide in the next step, which is known as carbon fixation.

The Energy

Most of the energy that powers life on Earth is captured and converted through photosynthesis.

Photosynthesis is a complex process used by plants and some bacteria to harness the energy of sunlight to convert water and carbon dioxide to produce sugar (glucose) and oxygen. It is a photosynthetic process, named after the Greek words for “light” and “synthesis,” which mean “putting together or to make.”

There are two sequential stages of photosynthesis: the light-dependent reactions and the light independent reactions (also known as the Calvin cycle). During the light-dependent reactions, the energy from sunlight is used by chlorophyll to drive a series of electron transfers that produce ATP and reduced nicotinamide adenine dinucleotide phosphate (NADPH).

The ATP and NADPH produced during the light-dependent reactions are then used to reduce carbon dioxide to organic carbon molecules, most notably glucose. This step is known as carbon fixation and is a critical part of the process. Without it, the Earth would quickly deplete of gases like carbon dioxide and oxygen that are needed for all living organisms to survive.

Types of Photosynthesis: Light-dependent, Light-independent, C3, C4

How Many Types of Photosynthesis Are There?

From the meats and dairy products in grocery stores to breads, cereals and pastas, most foods that people consume link back to photosynthesis. Light energy enters a plant through pigment molecules called chlorophyll, which then releases the energy by splitting water molecules.

Photosynthesis takes place in organelles called chloroplasts, found in cells of plants and algae. Chloroplasts contain stacked, disc-shaped structures called thylakoids.

1. Light-dependent

The light-dependent reactions (also called photosynthesis-reactions) use sunlight to convert water molecules into ATP and NADPH, which are energy-storing molecules. The products of these reactions are used by the light-independent reactions to “fix” carbon dioxide and assemble sugar molecules.

In the light-dependent reaction, one molecule of the pigment chlorophyll absorbs a photon and loses an electron. This electron passes to a special enzyme in the photosystem known as cytochrome b6f. The cytochrome b6f then moves the electron to the center of the photosystem where it is joined with another chlorophyll molecule and passed through an electron transport chain that eventually leads to reduced NADP and ATP.

This is the first step in photosynthesis. It also produces the oxygen that is present in Earth’s atmosphere. The process takes place in the thylakoid membranes of the chloroplasts. The thylakoid membranes contain the light-sensitive pigments chlorophyll and other proteins. Both prokaryotic and eukaryotic organisms carry out this process, including cyanobacteria (diatoms, dinoflagellates) and green algae and plants, such as vascular plants, bryophytes, pteridophytes, gymnosperms, and angiosperms.

2. Light-independent

The light-independent reactions of photosynthesis use the chemical energy harvested by the light-dependent reactions to assemble carbon dioxide into organic molecules, such as glucose. These reactions take place in the stroma, a colourless fluid that surrounds the thylakoid discs of chloroplasts. They are collectively known as the Calvin cycle.

In the light-independent reactions, the ATP and NADPH produced by the thylakoid membranes are used to reduce and phosphorylate atmospheric carbon dioxide into a carbohydrate molecule called 3-phosphoglycerate (3PG) or G3P. 3PG can then be incorporated into an organic molecule, such as glucose.

The reversible reaction that turns water into glucose is called the light-independent reaction of photosynthesis. It is also the final step of photosynthesis that produces oxygen, and it happens in the stroma of chloroplasts in the dark (without sunlight). The reversible reaction in this stage is called the Calvin cycle. It combines six molecules of carbon dioxide and 12 molecules of water to produce one molecule of glucose.

3. C3

This is the process that most plants use to make food from carbon dioxide and water. It’s also why our planet is blanketed with an oxygen-rich atmosphere. During photosynthesis, plants, algae and cyanobacteria convert sunlight into energy that they then store as organic molecules such as carbohydrates.

The C3 photosynthesis pathway is the dominant process used by most land plants, including cereals, rice, cotton and potatoes. It uses a process called the Calvin cycle to remove carbon from atmospheric CO2 and turn it into organic molecules.

C3 plants can benefit from increasing levels of carbon dioxide in the air resulting from the climate crisis, but this may be offset by increased temperature that could cause stomatal stress. Research is underway to improve C3 photosynthesis in order to ensure that crops can continue producing food. One approach is to introduce C4 traits into C3 plants. Glycine transport loops in bundle sheath cells can reduce photorespiratory CO2 loss and increase C3 photosynthesis at a given temperature by compartmentalizing glycine decarboxylation in the bundle sheath cells.

4. C4

In C4 photosynthesis, light energy is used to split water in a process called photosynthesis, producing O2 and electrons. These are used to produce the ATP and NADPH required for carbon fixation. This produces a four-carbon intermediate compound in the chloroplast of a thin-walled mesophyll cell, which is then pumped to a thick-walled bundle sheath cell where it is converted to CO2.

The CO2 diffuses out of the bundle sheath cells, and the ATP energy used to pump it back to the mesophyll cell for conversion to PEP makes this type of photosynthesis less efficient than C3. In addition, it requires low CO2 concentrations. Consequently, C4 plants can thrive in arid regions and habitats with high temperatures, low water availability, and saline soils. The evolution of C4 photosynthesis is thought to have been driven by a combination of conditions. The appearance of C4 plants in the evolutionary record coincides with periods of global aridification and declining atmospheric CO2. Gene duplication, neofunctionalization and carbon conservation selection are leading theories to explain its origin.

Energy Production in Photosynthesis: From Solar to Chemical Energy

How Much Energy Does Photosynthesis Produce?

Photosynthesis is the process by which plants, algae, and some bacteria convert solar energy into sugars and oxygen. This produces much of the food and building material that living things use, including cellulose, starches, and glucose.

Light energy strikes a photosynthetic pigment molecule (chlorophyll) and excites its electrons. The electrons then pass quickly from molecule to molecule until they reach an acceptor molecule that can capture them.

How much energy does a plant need?

All plant life on Earth relies on photosynthesis, which is the only biological process that can capture energy from sunlight and transform it into chemical compounds that power all of its metabolic processes. Sunlight energizes electrons, which are incorporated into long-lasting covalent bonds in sugar molecules like glucose and starch (and other sugars, fats, proteins, lignins, etc.).

During photosynthesis, plants take in water and carbon dioxide from the air and soil, transform them into sugars using redox reactions, and release oxygen into the atmosphere. In the process, they also store the energy they harvested in their own biomolecules.

The amount of energy a plant needs for photosynthesis depends on its light intensity and type, but in general it requires about eight einsteins (or maybe more) of solar energy to use one mole of carbon dioxide to produce glucose. During normal conditions, it takes around 10% of the available sunlight to get this amount of energy.

How much energy does a plant use?

During photosynthesis, solar energy is harvested from sunlight and converted to chemical energy in the form of glucose. This chemical energy is used by plants for growth and reproduction. Plants also use some of the energy for metabolic reactions such as cellular respiration.

Using special pigments, plants absorb different colors of light from the sun. Red and blue light are absorbed by chlorophyll, while green light is reflected. This is why leaves appear green.

When a plant uses sunlight to make food, it uses about 3% of the total energy in the light spectrum. This is a lot of energy, but it’s not all of the energy that a plant has to use.

The amount of energy that a plant uses can vary greatly depending on the weather. On a hot and dry day, plants may close their stomata to conserve water, which will reduce the amount of energy they can produce. This can have a negative impact on their productivity.

How much energy does a plant store?

Plants use two sequential stages of photosynthesis to convert sunlight into chemical energy. During the first, called the light-dependent reactions, the energy of a single photon is converted to stored chemical energy in molecules such as ATP and NADPH.

The second, called the light-independent reactions, is driven by the products of the light-dependent reactions and involves carbon dioxide molecule assembly. While the light-independent reactions don’t use light directly as a reactant, they need the energy harvested during the light-dependent reactions to function.

At the end of photosynthesis, a plant ends up with a glucose (C6H12O6) molecule, oxygen (O2) and water (H2O). This glucose molecule can then go on to become part of larger starch molecules or sugars, or it can be converted to cellulose, the material that plants use to build their cells. Almost all of the energy that humans consume comes from carbohydrate molecules produced by photosynthetic organisms. We also get some of our energy from breaking down these molecules during cellular respiration.

How much energy does a plant release?

The energy of sunlight is converted to chemical energy in a process called photosynthesis. This energy is stored in molecules such as glucose and oxygen. These molecules provide most of the energy for living things on Earth.

A plant uses some of its energy to move water from the roots through a tube-like structure called the xylem. Scientists have now estimated that this transpiration power is as much as 14% of the energy harvested by a plant during photosynthesis.

The amount of energy a plant can use depends on the conditions in which it grows. For example, if a plant absorbs too much energy from sunlight it will be unable to make enough sugar to meet its needs. This extra energy will either be rejected by the chloroplast or wasted as heat. If it is rejected, the thylakoids in which it is stored will lose their ability to transfer electrons between photosystems I and II. This will also reduce the rate of photosynthesis.
