Question

a part of the calvin cycle has been removed from the diagram on the right. what occurs at this stage of the cycle?

Explanation:

Step1: Understand the Calvin cycle stages

The Calvin cycle has three main stages: carbon fixation, reduction, and regeneration. The missing stage in the diagram is the reduction stage.

Step2: Recall the reduction stage process

In the reduction stage of the Calvin cycle, PGA (phosphoglyceric acid) is converted to G3P (glyceraldehyde - 3 - phosphate). This conversion requires ATP (which is hydrolyzed to ADP) and NADPH (which is oxidized to NADP⁺).

Answer:

In the reduction stage of the Calvin cycle, PGA (phosphoglyceric acid) is converted to G3P (glyceraldehyde - 3 - phosphate) using energy from ATP (ATP → ADP) and reducing power from NADPH (NADPH → NADP⁺).
