Q. I. Cyclic photophosphorylation needs PS-I and PS-II.
II. Cyclic photophosphorylation produces $NADPH + H ^{+}$ and ATP.
III. Cyclic photophosphorylation involves $H _{2} O$.
IV. Electrons are recycled in cyclic photophosphorylation.
Identify the correct and incorrect statements and select the option accordingly.

Photosynthesis in Higher Plants

Solution:

Statements I, II and III are incorrect, IV is correct. Incorrect statements can be corrected as
* Cyclic photophosphorylation operates only by PS-I.
* During cyclic photophosphorylation, 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.
