In light reaction, plastoquinone facilitates the transfer of electrons from

1

PS-II to Cyt b6fb_6f complex

2

Cyt b6fb_6f complex to PS-I

3

PS-I to NADP+^+

4

PS-I to ATP synthase

Step-by-Step Solution

After excitement, e−e^- is passed from PS-II (P680P_{680}) to primary electron acceptor (Pheophytin). From primary e−e^- acceptor, e−e^- is passed to plastoquinone. Plastoquinone (PQ) in turn transfer its e−e^- to Cyt b6fb_6f complex. Therefore plastoquinone facilitates the transfer of electrons from PS-II to Cyt b6fb_6f complex.
