How many ATP and NADPH 2 , are required for the synthesis of one molecule of Glucose during Calvin cycle?

Options

  1. A18 ATP and 16 NADPH 2
  2. B12 ATP and 12 NADPH 2
  3. C18 ATP and 12 NADPH 2
  4. D12 ATP and 16 NADPH 2

Correct answer

C. 18 ATP and 12 NADPH 2

Step-by-step solution

In the Calvin cycle, the reduction of one molecule of CO 2 requires 3 ATP and 2 NADPH 2 to complete one cycle. For the formation of one molecule of glucose, six turns of the Calvin cycle or six molecules of CO 2 are required. Hence, 18 ATP and 12 NADPH 2 are required for the synthesis of one molecule of glucose.
