Photo-phosphorylation:In the light reaction,addition of phosphate in the presence of light is called photo-phosphorylation.
Cyclic PhotophosphorylationNon−Cyclic PhotophosphorylationPhotophosphorylation occurring a cyclic electron transport called Cyclic Photophosphorylation.Photophosphorylation occurring a non−cyclic electron transport called Non−Cyclic Photophosphorylation.Only photosystem I is involved.Both photosystem I and II are involved.The active reaction centre is P700.The active reaction centre is P680.Electrons travel in a cyclic manner and travels back to PSI.Electrons travel in a non−cyclic manner and electrons from PSI is accepted by NADP.Only ATP is produced.Both ATP and NADPH are produced.Photolysis or hydrolysis is absent.Photolysis or hydrolysis is present.Oxygen is not evolvedOxygen is evolved as a by−productThe system is predominant in bacteria.The system is predominant in green plants.
