Where are ATP and NADPH used

1.	Where are ATP and NADPH used
Answer» ATP and NADPH act as energy driving factors in the biosynthetic phase (Calvin cycle) of photosynthesis. The Calvin cycle uses ATP and NADPH2 for the fixation and reduction of CO2 to form carbohydrates.Each Calvin cycle is completed in three phases—carboxylation, reduction and regeneration.During reduction or the glycolytic reversal phase, carbohydrate is formed at the expense of the photochemically made ATP and NADPH. Here, two molecules each of ATP and NADPH are required for fixing one molecule of CO2.
