Vedclass · Answer

(C) In the light-dependent reactions of photosynthesis,the process begins at $PS-II$ (Photosystem $II$).When the reaction center chlorophyll $a$ $(P_{680})$ absorbs light energy,it becomes excited and releases an electron.This high-energy electron is immediately captured by the primary electron acceptor,which is a molecule of pheophytin (a chlorophyll molecule lacking the central $Mg^{2+}$ ion).Following this,the electron is passed to a plastoquinone $(PQ)$,which is a quinone-based electron carrier.Among the given options,quinone is the correct category of the primary electron acceptor system involved in the electron transport chain following the initial excitation.

Which of the following is the primary electron acceptor from the chlorophyll molecule of $PS-II$?
