Question

Motor neurons release the neurotransmitter acetylcholine (ACh) and acetylcholinesterase degrades ACh in the synapse. If a neurophysiologist applies onchidal (a naturally occurring acetylcholinesterase inhibitor produced by the mollusc Onchidella binneyi) to a synapse, what would you expect to happen?
A) paralysis of muscle tissue
B) gradual loss of resting potential
C) decrease in the frequency of action potentials
D) convulsions due to constant muscle stimulation
E) no effect

Answer 1

Answer:

The correct answer is D) convulsions due to constant muscle stimulation.

Explanation:

As long as the muscle is overstimulated, there will be convulsions happening. Acetylcholine is a strong neurotransmitter that can cause this physiological response.
