BCH4024 F25 E2 Q14: Sоme аbоriginаl peоple use the compound tubocurаrine to apply to their poison arrows to paralyze their prey animals. When a prey animal is struck with one of these poison arrows, the acetylcholine receptor is blocked in its closed configuration by tubocurarine. Knowing that acetylcholine is a neurotransmitter that binds to the acetylcholine receptor, and that the receptors function as ligand-gated ion channels, mediating rapid response like muscle contraction, what is the mechanism for paralysis by tubocurarine?
