प्रश्न
The reactions of photosynthesis make up a biochemical pathway.
Explain how the biochemical pathway of photosynthesis recycles many of its own reactions and identify the recycled reactants.
उत्तर
Light reactions use light to synthesize ATP and NADPH2. The Calvin cycle uses these reactants to produce sugar from CO2 molecules.
This cycle then produces NAP + ADP + Pi which is used in the light reaction with H2O molecules to produce ATP and NADPH2 again.
