Question

Which one occurs both during cyclic and non-cyclic modes of photophosphorylation ?

Options

A.Involvement of both PS-I and PS-II
B.Felease of O2
C.Release of O2
D.Formation of NADPH

Solution

Cyclic photophosphorylation is that type of light energised ATP synthesis in which electron epelled by excitrd photocente is returned to it after passing over a chain of electron carriers. Non- cyclic photophosphorylation is that type of light energised ATP synthesis in which electron expelled by excited photocentre does not return to them. It involves two Photochemical Systems (PS-I and PS-II) and produces assimilatory power (ATP and NADPH).
