Once a pre-synaptic neuron has stopped firing, all of the following will
stop the local potential in the post-synaptic neuron except:
the neurotransmitter must diffuse away

Acetylcholinesterase (ACHE), the enzyme which breaks down
acetylcholine (ACh), is inhibited by many common pesticides. Which of
the following is likely to occur as a result?
the pre-synaptic neuron will become hyperpolarized
it will cause hyperpolarization in the post-synaptic neuron
post-synaptic neurons will not be able to stop producing action potentials
Unontic neurons will not be able to start producing action potentials
