A) cyclic photophosphorylation
B) non - cyclic photophosphorylation
C) oxidative photophosphorylation
D) none of the above.
Correct Answer: B
Solution :
: Phosphorylation takes place in two ways - cyclic and noncyclic. In noncyclic photo- phosphorylation high energy electrons released from P-680 (PSI) do not return to P-680 but pass through pheophytin, plastoquinone, cytochrome b6-f complex, plastocyanin and then enter P-700 and the excited electrons are used in the reduction of NADP to\[NADP{{H}_{2}}\]. When the electron from P- 700 is carried by\[FeS\](iron sulphur protein complex), Fd (ferredoxin), is reduced and with the help of Fd-NADP reductase, NADP is reduced to\[NADP{{H}_{2}}\].
