At the neuromuscular junction, the neurotransmitter acetylcholine (ACh) is degraded by acetylcholinesterase. If a neurophysiologist applies the naturally occurring acetylcholinesterase inhibitor, onchidal (produced by the mollusc Onchidella binneyi), to a synapse, what would you expect to happen?
A) paralysis of muscle tissue
B) convulsions due to constant muscle stimulation
C) decrease in the frequency of action potentials
D) no effect

The inhibition of acetylcholinesterase means that ACh will remain in the synaptic cleft for an extended period, continuously stimulating the muscle fibers. This can lead to sustained muscle contractions and convulsions.
