Vedclass · Answer

(A) The $Z$-scheme represents the light-dependent reactions of photosynthesis, specifically non-cyclic photophosphorylation.In this process, electrons are first excited in Photosystem $II$ $(PS II)$ by light energy.These electrons are then transferred through an electron transport system $(ETS)$ consisting of plastoquinone, cytochrome complex, and plastocyanin.From the $ETS$, the electrons reach Photosystem $I$ $(PS I)$.Finally, the excited electrons from $PS I$ are transferred to $NADP^+$ to form $NADPH + H^+$.Thus, the path is $PS II \rightarrow$ Electron Transport System $\rightarrow PS I \rightarrow NADP^+$.

State the path of $e^-$ in the $Z$-scheme.
