Characterize These Reactions Involved in the Calvin Cycle

Characterize these reactions involved in the Calvin cycle.

A) These are reactions involved in the regeneration of RuBP.The reactions include an exergonic reaction (ATP breaks down into ADP) and the reduction of the coenzyme NADPH.
B) These reactions are involved in the reduction of CO₂.Energy is required in the form of ATP,which is hydrolyzed to ADP.The substrate BPG is reduced,while the coenzyme NADPH is oxidized.
C) These reactions are involved in the fixation of CO_2. Energy is required in the form of ADP,which is hydrolyzed to ATP.The substrate BPG is oxidized,while the coenzyme NADPH is reduced.
D) These reactions are part of the light reactions in a noncyclic pathway.ATP and NADPH are used during these reactions.
