Question

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

(1) PS-II to Cytb_​​​6​​f complex

(2) Cytb_​​​6​​f complex to PS-I

(3) PS-I to NADP^​​​+

(4) PS-I to ATP synthase

​​​

Answer 1

Ans: (1) PS-II to Cytb₆f complex

Explanation: In light reaction of photosynthesis,  plastoquinone facilitates the transfer of electrons from PS-II to Cytb₆f complex which then reduces plastocyanin.
