How many turns of the Calvin cycle are required for the formation of three molecules of glucose?
- A.6
- B.3
- C.1
- D.18✓
Correct Answer
(D) 18
Solution & Explanation
One molecule of glucose requires 6 turns of the Calvin cycle (each turn fixes one CO₂; 6 CO₂ → one hexose). Therefore three glucose molecules require 6×3=18 turns.
