Detailed explanation-1: -Cyclic photophosphorylation happens only in the photosystem I but non-cyclic photophosphorylation occurs in both the photosystems I and II. In the cyclic photophosphorylation, only ATP is produced, whereas, in the non-cyclic photophosphorylation both NADPH and ATP are produced.
Detailed explanation-2: -In non-cyclic photophosphorylation the photolysis of water produces electrons that generate a proton motive force which is used to produce ATP, the electrons finally being used to reduce NADP+ to NADPH.
Detailed explanation-3: -Overall 7 ATP molecules are produced during non-cyclic photophosphorylation.
Detailed explanation-4: -Solution : In non-cyclic phosphorylation, electrons derived from the photolysis of water are raised to higher energy levles in PS-I, PS-II and pass along an electron transport chain of carrier molecule of NADP reduce .
Detailed explanation-5: -Solution : NADPH is generated through photosystem-II in non-cyclic photophosphorylation (which involves both PS-I and II) protons released from photolysis and electrons emitted from ‘P (700)‘ are ultimately passed on to ‘NADP(+)‘ resulting in the formation of NADPH.
