To fix 5 molecules of CO₂ during the Calvin cycle, what is the total number of ATP and NADPH molecules consumed respectively?

Step-by-step solution

In the Calvin cycle, the fixation of one molecule of CO₂ requires 3 molecules of ATP and 2 molecules of NADPH. For the fixation of 5 molecules of CO₂ , the total number of ATP molecules consumed is 5 3 = 15 ATP. The total number of NADPH molecules consumed is 5 2 = 10 NADPH. Thus, 15 ATP and 10 NADPH molecules are consumed. Answer: 15 ATP and 10 NADPH
