What is cyclic photophosphorylation?

Photosystem I has an excited electron escape to reach a higher energy level. It then moves down electron carriers, inducing chemiosmosis, and the electron eventually returns back to Photosystem I at a lower energy

Why does cyclic photophosphorylation occur?

When an organism has produced enough reduced NADP for the Calvin cycle, the cyclic version can continue to produce ATP through chemiosmosis. This process can occur without glucose or water

2 of 5

What are the products from cyclic photophosphorylation?

ATP

3 of 5

Why do plants not only cyclic photophosphorylate?

reduced NADP is also needed for the next part of the reaction, where glucose is made

4 of 5

Where does this take place?

In the thylakoid membrane of chloroplasts
