Question

difference between cyclic and non-cyclic photophosphorylation​

Answer 1

Answer:

Difference between cyclic and non-cyclic photophosphorylation

Cyclic photo-phosphorylation in photosynthesis light dependent reaction leads to the formation of ATP and NADPH, and the electrons go from water to PSII to PSI and eventually to NADPH. In non-cyclic photo-phosphorylation only some ATP is produced and the electrons go from PSII to PSI and back again.

Answer 2

Answer:

Cyclic photophosphorylation Non-cyclic photophosphorylation

1- It occurs in photosystem I. 1- It occurs in both photosystem I and photosystem II.

2- Only Atp is produced 2- Both ATP and NADPH are produced.

3- Electrons expelled by photosystem and return back. 3- Electrons expelled by photosystem but do not return back.

4- Photolysis of water does not occur. 4- Photolysis of water occur.

5- Oxygen is not released. 5- Oxygen is released.

6- Water is not consumed. 6- Water is consumed.
