Calvin cycle represents the phenomenon of:
Show Hint
- Oxidative Carboxylation
- Substrate Level Phosphorylation
- Dark Respiration
- Reductive Carboxylation
The Correct Option is D
Solution and Explanation
Calvin cycle fixes CO$_2$ through reductive carboxylation
Key steps:
Carboxylation: RuBP + CO$_2$ → 2 PGA
Reduction: PGA → G3P using NADPH and ATP
Regeneration: RuBP reformed
Process is reductive (consumes NADPH) and carboxylating
