Observe the given figure. Identify the different stages labelled with alphabets by selecting the correct option.
Options
- AA-Carboxylation, B-Regeneration, C-Reduction
- BA-Reduction, B-Decarboxylation, C-Regeneration
- CA-Carboxylation, B-Reduction, C-Regeneration
- DA-Reduction, B-Carboxylation, C-Regeneration
Correct answer
C. A-Carboxylation, B-Reduction, C-Regeneration
Step-by-step solution
The calvin cycle proceeds in three stages:
(A) Carboxylation, during which 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 acceptor ribulose-1,5-bisphosphate is formed again so that the cycle continues.
