As a research scientist, you measure the amount of atp and nadph consumed by the calvin cycle in 1 hour. you find that 30,000 molecules of atp were consumed, but only 20,000 molecules of nadph were consumed. where did the extra atp molecules come from

Cyclic electron flow

Explanation:

When light reacts with chlorophyll molecules during photosynthesis, there is an excitement of electrons causing an energy increase and they are passed into the cyclic electron flow.

Cyclic electron flow is observed in the chloroplasts of green plants. It results in the production of ATP but not O2 or NADPH.

This cyclic pathway may be used when a plant has enough NADPH but requires synthesis of ATP.

This is the source of the additional ATP.
