Acetylcholine is a neurotransmitter that binds to receptors on skeletal muscle cells. The receptor-signal complex brings about a series of events that result in contraction of skeletal muscle. Venom from black widow spiders causes an explosive release of acetylcholine. What would that do to its victims?
A) The victim's muscles would be unable to contract.
B) The victim's muscles would be unable to relax.
C) The victim's cell receptors would no longer be able to bind regulatory hormones.
D) The victim's cell receptors would be able to bind regulatory hormones but at a rate greatly exceeding normal rates.
