Question

Which one of the following is represented by Calvin cycle?

• A. Reductive carboxylation
• B. Oxidative carboxylation
• C. Photophosphorylation
• D. Oxidative phosphorylation

Answer 1

Answer: (A)

Reductive carboxylation

The Calvin cycle (also known as the Benson-Calvin cycle) is the set of chemical reactions that take place in chloroplast during photosynthesis. It involves 3 steps, they are carbon fixation, reduction and regeneration. The first two steps of Calvin cycle i.e reductive carboxylation is represented by Calvin cycle.

So, the correct answer is 'Reductive carboxylation'.
