Observe the given figure. Identify the different stages labelled with alphabets by selecting the correct option:

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

Step-by-Step Solution

According to the textbook (referring to Figure 11.8 representing the Calvin Cycle), the cycle proceeds in three distinct stages in order:

  1. Carboxylation (A): Fixation of CO2 into a stable organic intermediate.
  2. Reduction (B): A series of reactions that lead to the formation of glucose.
  3. Regeneration (C): Regeneration of the CO2 acceptor molecule RuBP [Sources 111, 114].
