Question

Write any six differences between cyclic photophosphorylation and non-cyclic photophosphorylation.

Answer 1

Cyclic photophosphorylation:

1. Cyclic photophosphorylation is explained as the synthesis of ATP integrate into electron transfer activated by the photosystem.

Non-cyclic photophosphorylation:

1. Non-cyclic photophosphorylation is a process which upshot in the movement of electrons in a non-cyclic manner for amalgamate ATP molecules using the energy from excited electrons presuming that by photosystem II.

S.no.	Cyclic photophosphorylation	Non-cyclic photophosphorylation
1.	Photosystem I is intricate in a cyclic photophosphorylation process.	Both photosystems I and II are intricate in the noncyclic photophosphorylation process.
2.	In cyclic photophosphorylation, P700 is known to be a spry reaction center.	In non-cyclic photophosphorylation, P680 is known to be a spry reaction centre.
3.	Electrons are prone to pass in a cyclic manner.	Electrons are prone to pass in a non-cyclic manner.
4.	NADPH does not get assembled.	NADPH gets assembled in noncyclic photophosphorylation.
5.	Oxygen does not get produced as a by-product.	Oxygen gets produced as a by-product.
6.	ATP molecules get created in this process.	ATP and NADPH are both molecules that get formed.
