Question

multiple choice question the adp and nadp+ produced by the calvin cycle are available to be used in ______. the reformation of rubp the light - dependent reactions the carbon fixation process the light - independent reactions

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 reformation of RuBP uses ATP and NADPH (not ADP and NADP⁺). The carbon fixation process is part of the Calvin cycle (light - independent) and uses ATP and NADPH. Light - independent reactions (Calvin cycle) produce ADP and NADP⁺, so they don't use them. So the ADP and NADP⁺ from the Calvin cycle are used in light - dependent reactions.

Answer:

B. the light - dependent reactions (assuming the options are labeled as A: the reformation of RuBP, B: the light - dependent reactions, C: the carbon fixation process, D: the light - independent reactions)
