Question

Which of the following phenomenon is represented by Calvin Cycle?

  1. Dark Phosphorylation
  2. Photo Phosphorylation
  3. Oxidative Phosphorylation
  4. Reductive Carboxylation

hintHint:

Reductive carboxylation

The correct answer is: Reductive Carboxylation


    The first phase is carboxylation, in which RUBP is converted into three carbon compounds. The next phase is a reduction, the 3PGA molecule made by fixing carbon, is converted into regular sugar molecule, glucose. The final stage is regeneration of RUBP. So the first two phases represent the reductive carboxylation.
