How many ATP and NADPH2, are required for the synthesis of one molecule of Glucose during Calvin cycle?

Options

  1. A18 ATP and 16 NADPH2
  2. B12 ATP and 12 NADPH2
  3. C18 ATP and 12 NADPH2
  4. D12 ATP and 16 NADPH2

Correct answer

C. 18 ATP and 12 NADPH2

Step-by-step solution

In the Calvin cycle, the reduction of one molecule of CO2 requires 3 ATP and 2 NADPH2 to complete one cycle. For the formation of one molecule of glucose, six turns of the Calvin cycle or six molecules of CO2 are required. Hence, 18 ATP and 12 NADPH2 are required for the synthesis of one molecule of glucose.
