A)inhibitory neurotransmitter and would produce an EPSP in the postsynaptic neuron.
B)inhibitory neurotransmitter and would produce an IPSP in the postsynaptic neuron.
C)excitatory neurotransmitter and would produce an EPSP in the postsynaptic neuron.
D)excitatory neurotransmitter and would produce an IPSP in the postsynaptic neuron.
E)excitatory neuropeptide and would hyperpolarize the postsynaptic neuron.

Question

Quizplus · Accepted Answer

A neurotransmitter that binds to an ionotropic receptor that contains a chloride channel would allow chloride ions to enter the cell, which would result in hyperpolarization of the postsynaptic neuron. This hyperpolarization would produce an inhibitory postsynaptic potential (IPSP), making it less likely for the neuron to fire an action potential. Therefore, the correct answer is B (inhibitory neurotransmitter and would produce an IPSP in the postsynaptic neuron).
