Detailed explanation-1: -So NADH is not a product of the light reaction of photosynthesis.

Detailed explanation-2: -NADH is not a product of light reaction of photosynthesis.

Detailed explanation-3: -Glucose is synthesised by utilising the assimilatory powers produced during light reaction. The synthesis of glucose occurs in stroma and this does not require light. Hence, the reaction for synthesis of glucose is a light-independent reaction.

Detailed explanation-4: -In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert six molecules of carbon dioxide into one sugar molecule, i.e. glucose.

Detailed explanation-5: -The light reactions and the Calvin cycle together convert light energy to the stored chemical energy of sugar. The plant can use the sugar to build other organic molecules. By converting light energy to chemical energy, photosynthesis is the first step in the flow of energy through an ecosystem.
