What is the significance of the Calvin pathway being cyclic?

Options

  1. AIt means RuBP is not used
  2. BIt means RuBP is regenerated
  3. CIt means the process is linear
  4. DIt means the pathway does not produce sugars

Correct answer

B. It means RuBP 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.
