Question

What is the purpose of cyclic Photophosphorylation?

Answer 1

Cyclic Photophosphorylation:

1. Photophosphorylation is a process of conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) by using light energy from photosynthesis.
2. There are 2 types of photophosphorylation reactions, namely, Cyclic and Noncyclic Photophosphorylation.
3. Cyclic uses only one Photosystem which is Photosystem I, whereas noncyclic uses two Photosystems, PS I and PS II.
4. Cyclic photophosphorylation in which electrons move in a cyclic way whereas in noncyclic it forms a Z shape.
5. Cyclic photophosphorylation takes place in the thylakoid membrane and makes use of Photosystem I and Chlorophyll P700.
6. The main purpose of Cyclic Photophosphorylation is the formation of Two ATP molecules from ADP and inorganic phosphate using only Photosystem I.
