Class 11 NEET Biology Photosynthesis in Higher Plants

For every CO2 molecule entering the Calvin cycle, 3 molecules of ATP and 2 of NADPH2 are required. To make one molecule of glucose, 6 turns of the cycle are required. Thus, ATP and NADPH2 molecules required for synthesis of one molecule of glucose during Calvin cycle will be →6×[
