Enzymatic degradation is the process by which an excess of a neurotransmitter called is removed from synapses .other neurotransmitters can be removed via the process of reuptake.

The correct answer is -   acetylcholine.

Explanation:

Acetylcholine is a neurotransmitter acts as a chemical message released by nerves to transmit signals from the brain to different parts. It is a chemical compound that is transferred from one nerve cell to others.

An excessive amount of this neurotransmitter acetylcholinesterase is enigmatically degraded by a specific enzyme that changes the structure of the neurotransmitter. This change in the structure results in not able to recognize by the receptor.

Thus, the correct answer is - acetylcholine.
