If a muscle were starved of ATP, at what stage in the contraction cycle would it be stopped? 8. The poison curare acts at the neuromuscular junction by blocking the acetylcholine receptor (acetylcholine is the neurtransmitter released at a neuromuscular junction). This prevents receptor signaling and the depolarization of the nerve cell membrane. What would be the effect of this poison on muscle function? At what step in the contraction cycle would contraction be blocked? David H. Bos (2009). This material can be used for non-profit educational purposes, if properly attributed.
