Question
Chapter 9.4, Problem 30AYP
Summary Introduction
To analyze:
The importance of acetylcholinesterase in the synaptic cleft.
Introduction:
The neurotransmitter is the molecule that allows the neurons to communicate with target and they require the presence of calcium ion for its release. The most common type of neurotransmitter is acetylcholine.
Acetylcholinesterase plays a key role in breaking down the acetylcholine present in the synaptic cleft to acetic acid and choline.
