Vedclass · Answer

(A) Option $A$ is correct. Stroma lamellae membranes lack both $PSII$ and $NADP$ reductase enzyme,which is why they only perform cyclic photophosphorylation.Option $B$ is incorrect because $F_1$ is the headpiece that protrudes into the stroma,while $F_0$ is embedded in the membrane.Option $C$ is incorrect because $T.W.$ Engelmann used Cladophora algae,not Chlamydomonas.Option $D$ is incorrect because the $C_4$ pathway starts with the carboxylation of $PEP$ (phosphoenolpyruvate) to form oxaloacetic acid,not decarboxylation.
