Which of the following 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
D)a drug that activates acetylcholinesterase

Question

Quizplus · Accepted Answer

Curare is a competitive antagonist of acetylcholine at the nicotinic receptor, meaning it prevents acetylcholine from binding and activating the receptor. Therefore, increasing the amount of acetylcholine in the synapse, as would occur with an acetylcholine reuptake promoter (A), or activating acetylcholinesterase (D) would not be effective in treating curare poisoning. Removing acetylcholine receptors from the postsynaptic cell (B) would also not be effective, as the problem is with the acetylcholine being blocked from binding to the receptor. Inhibiting acetylcholinesterase (C) would be effective in treating curare poisoning, as it increases the amount of acetylcholine available to bind to the receptor and counteract the effects of the curare.
