Vedclass · Answer

(D) $DCMU$ $(3-(3,4-dichlorophenyl)-1,1-dimethylurea)$ is a specific inhibitor of photosynthesis.It acts by binding to the $Q_B$ binding site of the $D1$ protein in $PS-II$.This binding prevents the transfer of electrons from the primary quinone acceptor $(Q_A)$ to the secondary quinone acceptor $(Q_B)$.Consequently,the electron flow from $PS-II$ to $PQ$ (plastoquinone) is blocked,thereby inhibiting non-cyclic photophosphorylation.

Which step of non-cyclic photophosphorylation is inhibited by $DCMU$?
