The herbicide DCMU kills the weeds because it inhibits

Question

The herbicide DCMU kills the weeds because it inhibits (A) respiration (B) CO2 fixation (C) cell division (D) NO32- uptake

Tardigrade Admin · Accepted Answer

DCMU (Dichlorophenyl dimethyl urea) is a herbicide which kills the weeds by inhibiting CO2 fixation as it is a strong inhibitor of photosystem II (P680). DCMU acts by blocking electron flow at the guanine acceptors of PS II, by competing for the binding site of plastoquinone.

Q. The herbicide $D CM U$ kills the weeds because it inhibits

respiration

$C O_{2}$ fixation

cell division

$N O_{3}^{2 -}$ uptake

$D CM U$ (Dichlorophenyl dimethyl urea) is a herbicide which kills the weeds by inhibiting $C O_{2}$ fixation as it is a strong inhibitor of photosystem $II (P_{680}) . D CM U$ acts by blocking electron flow at the guanine acceptors of $PS II$ , by competing for the binding site of plastoquinone.
