Question

Where does the cyclic electron flow occur?

Answer 1

The cyclic electron flow:

1. Photosynthesis requires cyclic electron flow.
2. It is used in the synthesis of ATP.
3. It only makes use of Photosystem I.
4. It doesn't produce NADPH or oxygen.
5. Photoexcited electrons from PSI P700 move through the b6f complex.
6. It then back to P700 in cyclic electron flow.
7. This cyclic electron flow is linked to the pumping of protons into the thylakoid lumen.
8. ATP synthesis occurs when protons flow down their electrochemical gradient through ATP synthase complexes.
9. The formation of ATP is a result of light-induced cyclic electron flow.
10. It is referred to as cyclic photophosphorylation.
