THE CALVIN CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the main stages of the Calvin cycle and in what order do they occur?
A
Reduction of RuBP, Carbon Fixation, and Regeneration
B
Carbon Fixation, Reduction, and Regeneration of RuBP
C
Phosphorylation, Reduction and Regeneration of RuBP
D
Reduction, phosphorylation, and Regeneration of RuBP
Explanation: 

Detailed explanation-1: -The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.

Detailed explanation-2: -The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue.

Detailed explanation-3: -So, the correct answer is ‘Carboxylation
