Detailed explanation-1: -As mentioned, acetylcholinesterase works by hydrolyzing the ester bond of acetylcholine to produce acetic acid and choline. This process regulates the presence of acetylcholine after it has been released from the nerve cell into the neuromuscular junction to prevent excessive muscle contraction.
Detailed explanation-2: -muscle contractions broken down by the enzyme acetylcholinesterase, which is anchored in the basement membrane, or diffuses out of the primary cleft, thus preventing constant stimulation of acetylcholine receptors.
Detailed explanation-3: -Acetylcholinesterase (AChE) is the primary enzyme responsible for the hydrolytic metabolism of the neurotransmitter acetylcholine (ACh) into choline and acetate.
