Loss of function in the enzyme acetylcholinesterase would result in which of the following?
A) stimulation of the production of acetylcholine
B) amplify or enhance the effect of ACh
C) inability to destroy and remove acetylcholine from the synaptic cleft
D) inability to release acetylcholine

Question

Quizplus · Accepted Answer

Acetylcholinesterase breaks down acetylcholine in the synaptic cleft, so a loss of this enzyme would result in an inability to destroy and remove acetylcholine from the synaptic cleft, leading to prolonged ACh signaling and potential toxic effects. A, B, and D are all incorrect because they imply increased ACh activity, which would not occur with loss of function in acetylcholinesterase.
