Question

As a research scientist, you measure the amount of ATP and NADPH used by the Calvin cycle in 3 hours. You find 9,000 molecules of ATP used, but only 6,000 molecules of NADPH. Where did the extra ATP molecules come from

Answer 1

The correct answer is - Cyclic flow.

Step-by-step explanation:

Cyclic electrons flow pumps proton in the lumen of thylakoid towards the concentration with the help of ATP synthase. This movement produces additional ATP.

These additional ATPs are come from cyclic electron flow, during light reaction come from cyclic electron flow, during light reaction.
