O₂ evolution is directly associated with:

Options

(a) PS I
(b) PS II
(c) phytochrome
(d) phycocyanin

Correct Answer:

PS II

Explanation:

During photolysis of water the electrons released are picked up by P₆₈₀ photocentre of photosystem II. The electron extruded by the photocentre of photosystem II picked up by the quencher phaeophytin. From here the electron passes over a series of carriers in a downhill journey losing its energy at every step. The major carriers are plastoquinone (PQ), cytochrome b-f complex and plastocyanin (PC). But passing over cytochrome complex, the electron loses sufficient energy for the creation of proton gradie
