Question

The enzyme that deactivates a specific neurotransmitter once it has been released into the synapse is acetylcholinesterase. It is responsible for breaking down acetylcholine, a neurotransmitter involved in muscle contraction, in the synaptic cleft. This process stops the continuous stimulation of the postsynaptic cell by acetylcholine, and allows the neurotransmitter to be efficiently recycled or eliminated.
