Quizplus · Accepted Answer

Botulism toxin and curare both affect the neurotransmitter acetylcholine. Botulism toxin prevents the release of acetylcholine at the neuromuscular junction, leading to paralysis, while curare blocks acetylcholine receptors at the neuromuscular junction, also causing paralysis.  The botulism toxin prevents the release of acetylcholine in the respiratory system, causing death by suffocation. Curare paralyzes lung muscles by occupying critical acetylcholine receptors so that the neurochemical cannot work as it normally does.
