Vedclass · Answer

(C) $DCMU$ (Dichlorophenyl dimethyl urea) is a potent herbicide.It acts by inhibiting the electron transport chain in photosynthesis.Specifically,$DCMU$ binds to the $Q_B$ binding site of the $D1$ protein in $PS-II$ (Photosystem $II$),thereby blocking electron flow from $PS-II$ to plastoquinone.This inhibition stops the light-dependent reactions,preventing the formation of $ATP$ and $NADPH$,which are essential for carbon dioxide fixation in the Calvin cycle.Therefore,it effectively kills the plant by inhibiting carbon dioxide fixation.
