NEET Biology question
With reference to three Calvin cycles (three CO2 molecules fixed), which option correctly gives: I. total gross PGAL (G3P) molecules produced, II. total ATP required for synthesis of these PGAL molecules, III. total NADPH required for the synthesis of these PGAL molecules?
Answer: (B)
Solution
Three turns of the Calvin cycle fix 3 CO2 onto 3 RuBP, giving 6 molecules of 3-PGA. Each 3-PGA is phosphorylated (1 ATP) and then reduced (1 NADPH) to glyceraldehyde-3-phosphate (PGAL/G3P).
