A)prolonging the action of acetylcholine at its synapses
B)decreasing the duration of action of acetylcholine at its synapses
C)decreasing the synthesis of acetylcholine by the presynaptic cell
D)increasing the synthesis of acetylcholine by the presynaptic cell

Question

A drug that inhibits the action of the enzyme acetylcholinesterase will have the effect of ____.​
A)prolonging the action of acetylcholine at its synapses
B)​decreasing the duration of action of acetylcholine at its synapses
C)​decreasing the synthesis of acetylcholine by the presynaptic cell
D)increasing the synthesis of acetylcholine by the presynaptic cell

Quizplus · Accepted Answer

Acetylcholinesterase is responsible for breaking down acetylcholine after it has been released by the presynaptic cell. Inhibiting the action of this enzyme will prevent its breakdown, leading to a prolonged action of acetylcholine at its synapses. This can have a variety of effects, depending on the location and function of the synapses involved.
