After reading the paragraphs below, answer the questions that follow.
Curare is a potent neurotoxin extracted from the Strychnos toxifera plant in Central and South America. Indigenous peoples of South America applied curare to arrows, which they used to hunt and kill animals. Curare acts at synapses between motor neurons and skeletal muscle cells. When a motor neuron synapses with a skeletal muscle cell, the skeletal muscle cell may be stimulated or inhibited just like postsynaptic neurons are. Curare acts by binding temporarily to acetylcholine receptors on the postsynaptic cell and prevents acetylcholine from binding.
-Which could be an effective treatment for curare poisoning?
A) a drug that promotes acetylcholine reuptake into the presynaptic cells
B) a drug that removes acetylcholine receptors from the postsynaptic cell
C) a drug that inhibits acetylcholinesterase (an enzyme that breaks down acetylcholine)

Question

Quizplus · Accepted Answer

Curare works by preventing acetylcholine from binding to receptors on the postsynaptic cell. This suggests that inhibiting the enzyme that breaks down acetylcholine (acetylcholinesterase) would be a treatment that could help counteract the effects of curare. Choices A and B are unlikely to be effective since they do not address the issue of acetylcholine binding at the synapse.
