Question
Which of the following phenomenon is represented by Calvin Cycle?
- Dark Phosphorylation
- Photo Phosphorylation
- Oxidative Phosphorylation
- Reductive Carboxylation
Hint:
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.
