Question

Is the Calvin cycle a cyclic or linear pathway?

Answer 1

Calvin cycle:

1. It is a metabolic pathway in which carbon enters in the form of CO₂ and leaves in the form of sugar.
2. The pathway operates in a cyclical manner.
3. It occurs in all photosynthetic plants.
4. It involves 3 steps - carboxylation, reduction, and regeneration.
5. In the Calvin cycle, ATP is spent and NADPH₂ is consumed.
6. It ultimately leads to the synthesis of sugars.
