Question
Six turns of calvin cycle are required to generate one mole of glucose. Explain.
Advertisements
Solution
During the Calvin cycle, 3 molecules of ATP and 2 molecules of NADPH are required for the reduction of one molecule of CO2. Since glucose is a 6-carbon compound, 6 molecules of carbon dioxide are required to prepare one molecule of glucose. Hence, six turns of the calvin cycle are needed to generate one mole of glucose. Hence a total of 18 ATP and 12 NADPH is required for the synthesis of one molecule of glucose.
