Answer: True

Explanation: Acetylcholinesterase is an enzyme in the human body. It breaks down acetylcholine into an inefficient and ineffective form. This breakdown of acetlycholine declines nerve cell communications in the body. Acetylcholine is splitted to acetate and choline.

However, there are inhibitors that stops and prevents acetylcholinesterase from breaking down acetylcholine into choline and acetate, this inhibitors keep the level of acetylcholine in the body normal and functional so as to promote cell signaling and information transmission in the body.

Answer:

True

Explanation:

The action of aceetylcholine in the synaptic cleft is normally terminated by metabolism to acetate and choline by the enzyme acetylcholinesterase and the stimulation of the post-synaptic cell is stopped.

This esterase is anchored to the postsynaptic cell but acts extracellularly.

The products of acetylcholinesterase are not released , infact they are reabsorbed to make more ACh.

Hence, the statement the enzyme acetylcholinesterase, located in the synaptic cleft and on the postsynaptic membrane, breaks ACh down into acetate and choline, thereby stopping the stimulation of a postsynaptic cell is true.
