$B$ and $D$

Vedclass · Answer

(D) Statement $(A)$ is incorrect because the $Z$-scheme involves both $PS-II$ and $PSI$.Statement $(B)$ is correct because cyclic photophosphorylation involves only $PSI$ where electrons circulate back to the reaction center.Statement $(C)$ is incorrect because cyclic photophosphorylation produces only $ATP$,not $NADPH_2$. $NADPH_2$ is produced in non-cyclic photophosphorylation.Statement $(D)$ is correct because the stroma lamellae membranes lack $PS-II$ as well as the enzyme $NADP$ reductase $(FNR)$.Therefore,statements $(B)$ and $(D)$ are correct.
