Vedclass · Answer

(A) In noncyclic photophosphorylation,both $PS-II$ and $PS-I$ are involved.$PS-II$ contains a reaction center chlorophyll-$a$ molecule known as $P_{680}$,which absorbs light at $680 \ nm$.When light energy is absorbed by the antenna pigments,it is transferred to the reaction center.The $P_{680}$ molecule is the first to be excited,losing an electron to the primary electron acceptor.Therefore,$P_{680}$ is the pigment molecule that is first excited in the noncyclic electron transport chain.

In noncyclic photophosphorylation,the pigment molecule first excited is
