Vedclass · Answer

(B) Cyclic photophosphorylation occurs in the stroma lamellae due to the following reasons:- The stroma lamellae membranes lack $PS-II$ and the enzyme $NADP$ reductase.- Because $PS-II$ is absent,water splitting (photolysis) does not occur,and there is no supply of electrons from water.- Since $NADP$ reductase is absent,the excited electrons from $PS-I$ cannot be used to reduce $NADP^+$ to $NADPH$.- Consequently,the excited electrons are cycled back to the $PS-I$ complex through the electron transport chain,resulting in the synthesis of $ATP$ only.
