Which of the following processes occurs during the second phase, the reduction phase, of the Calvin cycle?

a) RuBP regeneration
b) Molecular oxygen production
c) Carbon fixation
d) NADPH production
e) G3P production

Answer :

Final answer:

During the reduction phase of the Calvin cycle, e) G3P is produced using ATP and NADPH.

Explanation:

The reduction phase of the Calvin cycle involves the production of G3P (glyceraldehyde-3-phosphate) using ATP and NADPH, which are products of the light-dependent reactions.

During this phase, six molecules of both ATP and NADPH are used to convert 3-PGA (3-phosphoglycerate) into G3P. G3P can then be used to build more complex carbohydrate molecules, such as glucose.
