What Are the Reactants of Photosynthesis? | Sciencing

The chemical equation is written below which summarizes the chemical reactions of photosynthesis.

Which molecules are reactants in photosynthesis

Immediatelyafter exposure to 14CO2, the plant's photosynthetic tissue iskilled by immersing it in boiling alcohol, and all of the biochemical reactions cease.

What are the Reactants and Products in the Process of Photosynthesis

In the presence of the enzyme Rubisco,one molecule of CO2 is combined with one molecule of RuBP, and the first product of this reaction is two molecules of PGA.

Needless to mention, the above formula for photosynthesis is not balanced, as there is only one atom of carbon in the reactant side, while there are 6 carbon atoms in the product side.

The enlargement is shown below.




The light reactions of photosynthesis are actually an electron pumping system located on the thylakoids of the chloroplast.

Note: the light reaction does not take place inside of the thylakoid, only on its surface.




There are special pigments found in a chloroplast, which function in photosynthesis, that are found nowhere else in a plant.

Photosynthesis is a process used by ..






The complex process of photosynthesis actually consists of TWO interrelated complex reactions -- the LIGHT and DARK reactions.

The ATP energy produced in the light reaction is actually captured light energy which will end up STORED in a glucose molecule.




The dark reactions are often called "The Calvin Cycle" after the botanist Melvin Calvin who discovered the chemical reactions that occur in the dark reaction.

Light-independent reactions - Wikipedia

In summary, photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds. In plants, photosynthesis typically occurs within the chloroplasts located in plant . Photosynthesis consists of two stages, the light reactions and the dark reactions. The light reactions convert light into energy (ATP and NADHP) and the dark reactions use the energy and carbon dioxide to produce sugar. For a review of photosynthesis, take the .

The next stage in the Calvin cycle is to regenerate RuBP

This process is known as carbon fixation or the . The Calvin cycle has three main stages: carbon fixation, reduction, and regeneration. In carbon fixation, carbon dioxide is combined with a 5-carbon sugar [ribulose1,5-biphosphate (RuBP)] creating a 6-carbon sugar. In the reduction stage, ATP and NADPH produced in the light reaction stage are used to convert the 6-carbon sugar into two molecules of a 3-carbon , glyceraldehyde 3-phosphate. Glyceraldehyde 3-phosphate is used to make glucose and fructose. These two molecules (glucose and fructose) combine to make sucrose or sugar. In the regeneration stage, some molecules of glyceraldehyde 3-phosphate are combined with ATP and are converted back into the 5-carbon sugar RuBP. With the cycle complete, RuBP is available to be combined with carbon dioxide to begin the cycle over again.
