Photphosphorylation is

Options

(a) synthesis of ATP in presence of light
(b) breakdown of ATP to give energy
(c) photolysis of water
(d) synthesis of starch

Correct Answer:

synthesis of ATP in presence of light

Explanation:

In photosphosphorylation, synthesis of ATP is the light driven or light energised process. It was discovered by Arnon et al in 1954. It is of two main types: cycle and non cyclic. In cyclic photophosphorylation PSI takes part and only ATP be formed. In non-cyclic PSI and PSII both take part in which ATP and NADPH₂ formed.
