Q. I. Cyclic photophosphorylation needs PS-I and PS-II II. Cyclic photophosphorylation produced NADPH + $H^{+}$ and ATP III. Cyclic photophosphorylation involves $H_{2}O$ IV. Electrons are recycled in cyclic photophosphorylation Identify the correct and incorrect statement and select the option accordingly
A) I, II and III are incorrect, IV in correct
B) I, II and IV are incorrect, III is correct
C) I, II and III are incorrect, II in correct
D) IV, III and Ii are incorrect, I in correct
Explanation
Cyclic phosphorylation operates only by PS-I during cyclic phosphorylation only. ATP formation takes place and recyclation of electrons also occurs. Unlike, the non-cyclic phosphorylation, splitting of $H_{2}O$ does not take place in the cyclic phosphorylation
