Question

the adp and nadp+ produced by the calvin cycle are available to be used in ______.

the light-independent reactions

the light-dependent reactions

the reformation of rubp

the carbon fixation process

Explanation:

1. Recall the processes of photosynthesis: The Calvin cycle (light - independent reactions) produces ADP and NADP⁺.
2. Analyze the role of ADP and NADP⁺: ADP is used to make ATP and NADP⁺ is used to make NADPH in the light - dependent reactions. The light - independent reactions (Calvin cycle) use ATP and NADPH from light - dependent reactions. The reformation of RuBP and carbon fixation are parts of the Calvin cycle (light - independent reactions) which produce ADP and NADP⁺, not use them. So the ADP and NADP⁺ produced by the Calvin cycle are used in the light - dependent reactions.

Answer:

B. the light - dependent reactions
