who is the primary electron acceptor in noncyclic photophoshorylation?

Hai souparnika,
You should first know the difference
Non-Cyclic photophosphorylation involves both PSII and PSI
Cyclic involves phtophosphorylation PS-I only.
In Non cyclic the first e^- acceptor is Pheophytin.
Iam here with attching both cyclic and non cyclic diagrams go through them for better understanding.

Hi dear, Non cyclic as well as cylic photophosporylation both occurs on thalakoid membrane. In non cyclic primary electron acceptor is coenzyme quinone

Quinone is the primary acceptor of electron in noncyclic photophosphorylation of plant where both ps1 ps2 present

Phaeophytin is pr. Acceptor of electron in PSII. FRS is pr. Acceptor in PSI. FRS is a iron sulphur protein complex membrane bound protein
