Vedclass · Answer

(A) In the light-dependent reactions of photosynthesis,when the reaction center of Photosystem-$II$ $(P_{680})$ absorbs light,it becomes excited and releases an electron.This high-energy electron is immediately captured by the primary electron acceptor,which is Pheophytin.However,among the given options,the electron is subsequently transferred to a plastoquinone $(PQ)$,which acts as the primary stable electron acceptor in the electron transport chain.Therefore,in the context of standard textbook options provided,Quinone (specifically Plastoquinone) is the correct answer.

The first electron acceptor from an excited chlorophyll molecule of Photosystem-$II$ is .......
