Which of these is NOT a direct product of the Calvin cycle?
Show answer and explanation
Correct answer: Oxygen gas
Oxygen is a byproduct of the light-dependent reactions (photolysis of water) in the thylakoid. The Calvin cycle produces triose phosphate, and regenerates ADP and NADP+ to be reused by light reactions.
