Question

In the Calvin cycle for the fixation of 5 molecules of CO2, how many ATP and NADPH are required in the reduction step? (A) 18 ATP and 12 NADPH (B) 15 ATP and 10 NADPH (C) 10 ATP and 10 NADPH (D) 3 ATP and 2 NADPH

Tardigrade Admin · Accepted Answer

During the Calvin cycle, for fixing one molecule of CO2, 2 ATP and 2 NADPH are required in the reduction step. Hence, for the fixation of 5 molecules of CO2, 10 ATP, and 10 NADPH are required in the reduction step.

Q. In the Calvin cycle for the fixation of 5 molecules of CO₂, how many ATP and NADPH are required in the reduction step?

18 ATP and 12 NADPH

15 ATP and 10 NADPH

10 ATP and 10 NADPH

3 ATP and 2 NADPH
