In light reaction, plastoquinone facilitates the transfer of electrons from:

Options

A. PS-II to Cyt`b_6`f complex
B. Cyt`b_6`f complex to PS-I
C. PS-I to NAD`P^+`
D. PS-I to ATP synthase

Answer

A

Explanation

After excitement, `e^-` is passed from PS-II `(P_680)` to primary electron acceptor (Pheophytin). From primary `e^-` acceptor, `e^-` is passed to plastoquinone (PQ) . In turn, plastoquinone transfer its `e^-` to Cytb6f complex. So, plastoquinone facilitates the transfer of electrons from PS-II to Cytb6f complex.
