NEET Botany Question (2024) — Solution
Options
- A. A-Carboxylation, B-Regeneration, C-Reduction
- B. A-Reduction, B-Decarboxylation, C-Regeneration
- C. A-Carboxylation, B-Reduction, C-Regeneration
- D. A-Reduction, B-Carboxylation, C-Regeneration
Answer
C. A-Carboxylation, B-Reduction, C-Regeneration
Step-by-step solution
The calvin cycle proceeds in three stages: (A) Carboxylation, during which CO _2 combines with ribulose-1,5-bisphosphate. (B) Reduction, during which carbohydrate is formed at the expense of the photochemically made ATP and NADPH. (C) Regeneration during which the CO _2 acceptor ribulose-1,5-bisphosphate is formed again so that the cycle continues.
