Describe non cyclic photophosphorylation
Answers
"Photophosphorylation refers to the ""process"" by which light is used in plants to synthesize adenosine-tri-phosphate molecules by transferring phosphate moieties to the adenosine-di-phosphate molecules. It is called as ""non-cyclic photophosphorylation"" if the transfer of electrons between the photosystems I and II occur in a ""non-cyclic manner"".
These are also called as light reactions as it happens in the ""presence of light"" and it occurs in the ""grana"" of the chloroplasts.In this process, the electrons from P680 of photosystem II are irreversibly transferred to ""P700 of photosystem I"". Then the electrons from ""P700"" are transferred to a primary acceptor and finally to NADP. Ultimately, these ""electrons"" combine with the ""protons"", produced by photolysis of water, and ""reduce"" ""NADP"" to ""NADPH_2"".
