During the operation of non-cyclic photophosphorylation, the immediate source of electron to P₇₀₀ is

Options

(a) cyt f
(b) PC
(c) PQ
(d) Fd

Correct Answer:

PC

Explanation:

Noncyclic photophosphosphosrylation comprises both PS-I and PS-II. In this extruded electron passes through a series of electron carriers – phaeophytin, PQ, cytochrome b-f complex and plastocyanin (PC). Then the electron is handed over to P₇ₒₒ from PC.
