What happens to RuBP in the Calvin pathway?

Options

  1. AIt is broken down and not regenerated
  2. BIt is converted into ATP
  3. CIt is regenerated
  4. DIt is converted into NADPH

Correct answer

C. It is regenerated

Step-by-step solution

Calvin and his co-workers then worked out the whole pathway and showed that the pathway operated in a cyclic manner; the RuBP was regenerated . Let us now see how the Calvin pathway operates and where the sugar is synthesised. Let us at the outset understand very clearly that the Calvin pathway occurs in all photosynthetic plants; it does not matter whether they have C3 or C4 (or any other) pathways.
