Quizplus · Accepted Answer

Curare is a poison that works by blocking receptor sites and acting as an antagonist for acetylcholine, which is a neurotransmitter that is responsible for muscle contraction. When the receptor sites are blocked, the acetylcholine cannot bind to them and signal for the muscles to contract, leading to paralysis.
