Question

Acetylcholine is found in the synapse between muscles cells and neurons. It can be broken down by the enzyme acetylcholinesterase. Which of the following describes what happens if acetylcholinesterase is inhibited?

Acetylcholine will continue to be activated.
Acetylcholine will be prematurely terminated.
Acetylcholine will lose specificity of the response.
Acetylcholine will be inhibited.

Answer 1

Answer:

Acetylcholine will continue to be activated.

Explanation:

When we inhibit acetylcholinesterase with an acetylcholinesterase inhibitor (AChEI) it will inhibit acetylcholinesterase from breaking down acetylcholine into choline and acetate. This will increase the level and the duration of the neurotransmitter in the CNS, autonomic ganglia, and neuromuscular junctions.
