Question

Sort the steps of Calvin cycle in the order they take place.

• A. Carboxylation
• B. Regeneration
• C. Reduction
• D. Cycle continues

Answer 1

Calvin cycle involves three phases which occur in the sequence - carboxylation, reduction and regeneration. In carboxylation phase RUBP accepts $C{O}_2$ and PGA is produced. In reduction phase PGA is reduced to triose phosphate and finally, in regeneration phase RuBP is regenerated.
