A substance is found to have the same effect as acetylcholinesterase, but acts at a much faster rate. What effect would this substance have at a cholinergic synapse?
A) It would greatly reduce synaptic communication by depleting ACh levels in the synaptic cleft.
B) It would enhance synaptic communication by concentrating ACh in the synaptic cleft.
C) It reduce synaptic communication by destroying ACh receptors on the post-synaptic membrane.
D) It would enhance synaptic communication by increasing the post-synaptic cells' sensitivity to ACh.

Question

Quizplus · Accepted Answer

Acetylcholinesterase breaks down acetylcholine (ACh) in the synaptic cleft, terminating the signal. A substance that acts like acetylcholinesterase but faster would deplete ACh levels more quickly, reducing synaptic communication.
