Vedclass · Answer

(B) $DCMU$ ($3$-($3$,$4$-dichlorophenyl)$-1,1-$dimethylurea) is a well-known herbicide that specifically inhibits photosynthesis.It acts by binding to the $Q_B$ binding site of the $D1$ protein in the $PS-II$ complex.By blocking this site,it prevents the transfer of electrons from $Q_A$ to $Q_B$,thereby halting the electron transport chain at the level of $PS-II$.Consequently,the light-dependent reactions of photosynthesis are inhibited.

$DCMU$ ($3$-($3$,$4$-dichlorophenyl)$-1,1-$dimethylurea) is a chemical that acts as an inhibitor of photosynthesis. What is its specific mode of action?
