Synthesis of each molecule of glucose in photosynthesis involves:
  1. (A)10 molecules of ATP
  2. (B)8 molecules of ATP
  3. (C)6 molecules of ATP
  4. (D)18 molecules of ATP✓ Correct

Answer: (D)

Solution

Building one molecule of glucose runs through the Calvin cycle, which spends the ATP and NADPH generated by the light reactions. Fixing six molecules of into one glucose calls for eighteen molecules of ATP, so the synthesis of each glucose involves ATP.
