The Calvin cycle would eventually halt without
- Acheck_circle
Continuous supply of ATP and NADPH from the light reactions
- B
Continuous supply of glucose and starch from the chloroplast
- C
Continuous supply of CO₂ and O₂ from the atmosphere
- D
Continuous supply of NADH and FADH₂ from the mitochondria
Explanation
Calvin enzymes can run in the dark briefly using stored ATP/NADPH pools, but they're depleted quickly without the light reactions replenishing them.
