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)Muscles would be unable to contract.
B)Muscles would be unable to relax.
C)Cell receptors would no longer be able to bind regulatory hormones.
D)G-protein receptors would all be inactivated.

Question

Quizplus · Accepted Answer

The explosive release of acetylcholine from black widow spider venom would result in sustained muscle contractions, as the receptors on the skeletal muscle cells would be continuously stimulated by the neurotransmitter. This could lead to muscle spasms, cramps, and in severe cases, paralysis. Therefore, choice B is the best answer.
