Question

diff between cyclic and non cyclic phosphorylation

Answer 1

HEY HERE IS YOUR ANSWER

CYCLIC PHOSPHORYLATION:-

1:- ONLY PHOTOSYSTEM IS INVOLVED.
2:- ELECTRONS TRAVELS IN A CYCLIC MANNER.
3:- ONLY ATP IS PRODUCED.
4:- OXYGEN IS NOT EVOLVED.
5:- PHOTOLYSIS OR WATER SPLITTING IS ABSENT.


NON CYCLIC PHOSPHORYLATION

1:- BOTH PHOTOSYSTEM 1ST AND 2ND ARE INVOLVED
2:- ELECTRONS TRAVELS IN A NON CYCLIC MANNER.
3:- BOTH ATP AND NADPH ARE PRODUCED.
4:- PHOTOLYSIS OR WATER SPLITTING IS PRESENT.
5:- OXYGEN IS EVOLVED AS A BY PRODUCT.

Answer 2

Hello!!

$\huge\mathfrak\blue{answer}$

⭕ Cyclic photophosphorylation :

➡️ It is performed by photosystem l independently.

➡️ An external source of electrons is not required.

➡️ It is not concerned with photolysis of water. Therefore, no oxygen is evolved.

➡️ It synthesis ATP only.

➡️ It occurs mostly in stroma lamellae membrane.

⭕ Non - Cyclic photophosphorylation :

➡️ It is performed by collaboration of both photosystem l and ll.

➡️ The process requires an external electron donor.

➡️ It is connected with photolysis of water and liberation of oxygen occurs.

➡️ It is not only connected with ADP synthesis, but also with production of NADPH.

➡️ It occurs in the granal thylakoids.
