Vedclass · Answer

(A) In the light-dependent reactions of photosynthesis,the electron transport chain involves a series of carriers.Plastoquinone $(PQ)$ acts as a mobile electron carrier.It accepts electrons from the primary electron acceptor of $PS-II$ (pheophytin) and transfers them to the $Cytb_{6}f$ complex.This movement of electrons through the $Cytb_{6}f$ complex is coupled with the pumping of protons into the thylakoid lumen,creating a proton gradient.

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