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 tissueb) convulsions due to constant muscle stimulationc) decrease in the frequency of action potentialsd) no effect

B convulsions due to constant muscle stimulation

Explanation:

            this is due to  Hyperpolarization at the  axonal cell membrane from continuous influx of sodium ions .

Normally acetylcholine is an exictatory  neurotranmitter, if an inhibitor is applied to block effects of acetylcholinesterase; the action potential will continue to generate , leading to continuous excitation, ( rapid contraction of muscles from increasing action potential, leading to convulsion.

So far  nothing to stop the excitatory neurotransmitter. (acetylcholine stimulation at the receptors of neuromuscular junction of post synaptic neuron.
