Biology

The main products of the light-dependent reactions that are used in the Calvin cycle are ATP and NADPH.

The light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts and are driven by light energy. During these reactions:

The oxygen produced as a result of this photolysis of water is released into the atmosphere through the stomata (small openings on the surface of plant leaves).

ATP is produced by photophosphorylation, which involves the use of light energy to generate ATP through the electron transport chain and ATP synthase.

NADPH is produced when electrons from water molecules, excited by light energy in photosystem I, are transferred to NADP⁺, reducing it to NADPH.

ATP and NADPH are then transported to the stroma of the chloroplasts, w...
