Question
Which of the following is the correct sequence of reaction in Calvin Cycle?
- Carboxylation →Reduction → Regeneration
- Reduction→ Carboxylation → Regeneration
- Regeneration →Reduction→Carboxylation
- Reduction → Regeneration →Carboxylation
Hint:
Carboxylation ---> Reduction ---> Regeneration
The correct answer is: Carboxylation →Reduction → Regeneration
The Calvin cycle is classified into three phases:
The first phase is carboxylation, in which RUBP is converted into two 3 carbon compounds.
The next phase is a reduction, the 3 PGA molecule, made by fixing carbon, is converted into a regular sugar molecule, glucose.
The final stage is regeneration of RUBP.
