Which elements are essential for the photophosphorylation?

Options

(a) Mg and P
(b) Zn and I
(c) K and Cl
(d) Mn and Cl

Correct Answer:

Mn and Cl

Explanation:

Photophosphorylation can be of two types-cyclic and non-cyclic. During non-chyclic photophosphorylation, PS II picks electrons obtained by photolysis of water carried out by an associated oxygen evolving complex (containing Mn²⁺⁺, Ca²⁺, Cl⁻). When photocentre of PS II (P₆₈₀) absorbs light energy the electrons are extruded and pass through a series of electron cariers and are handed over to PS I by plastocyanin where they are again excited by absorption of light energy by photocentre (P₇₀₀) and finally rea
