Cholinesterase is an enzyme that breaks down acetylcholine in the synapse. What would be the result if acetylcholine was released at a synapse, but no cholinesterase was present? O a. The postsynaptic neuron would not be stimulated. Ob. A single nerve impulse would be generated in the postsynaptic neuron. Oc. The acetylcholine would diffuse more rapidly across the synaptic cleft. d. The postsynaptic neuron would remain in a constant state of depolarization.
