Motor Neurons Release the Neurotransmitter Acetylcholine (ACh), and Acetylcholinesterase Degrades

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 mollusk Onchidella binneyi) to a synapse, what would you expect to happen?

A) paralysis of muscle tissue
B) gradual loss of resting potential
C) convulsions due to constant muscle stimulation
D) decrease in the frequency of action potentials
E) no effect
