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

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.
