Statement-$I$ & Statement-$II$ both are incorrect.

Vedclass · Answer

(D) Statement-$I$ is incorrect because when $PS-II$ is functional,it involves non-cyclic photophosphorylation ($Z$-scheme),where electrons are not circulated within the photosystem but are transferred from water to $NADP^+$. Cyclic photophosphorylation occurs only when $PS-I$ is functional and electrons circulate within $PS-I$.Statement-$II$ is incorrect because stroma lamellae membranes lack $PS-II$ and $NADP$ reductase enzyme,but they do contain $PS-I$.

Statement-$I$: When $PS-II$ is functional,the electron is circulated within the photosystem and photophosphorylation occurs due to the cyclic flow of electrons.
Statement-$II$: The stroma lamellae membranes lack $PS-I$ as well as $NADP$ reductase enzyme.
