Answer Key / Explanation : (c) -

(c)

The Calvin cycle proceeds in three stages (1) carboxylation, during which  combines with ribulose 1, 5-bisphosphate; (2) reduction, during which carbohydrate are formed at the expense of the photochemically made ATP and NADPH; and (3)  regeneration during,  acceptor is ribulose 1, 5-bisphosphate is formed again so that the cycle continues. Regeneration of the  acceptor molecule, RuBP is crucial if the cycle is to continue uninterrupted. The regeneration steps require one ATP for phosphorylation to form RuBP
