Read the following four statements and select the right option(a) Photosynthesis is an oxidation-reduction process(b) The principal function of light dependent reactions of photosynthesis is to generate NADPH and ATP required for carbon oxidation(c ) The electrons from Cyt f are picked up by a copper binding protein, plastocyanin(d) Quantum yield is defined as the number photons required to evolve one molecule of O2.

Photosynthesis is fundamentally an oxidation–reduction reaction.The principal function of the light-dependent reactions of photosynthesis is therefore to generate the NADPH and ATP required for carbon reduction.From Cyt f , the electrons are picked up by a copper-binding protein, plastocyanin (PC). PC is a small peripheral protein that is able to diffuse freely along the lumenal surface of the thylakoid membrane. Quantum yield of oxygen evolution is, number of molecules of O2 evolved per photon absorbed and quantum requirement for oxygen evolution is defined as the number photons required to evolve one molecule of O2.
