A neurotransmitter can be either excitatory or inhibitory depending on the postsynaptic receptor.

Question

Quizplus · Accepted Answer

This statement is true. Whether a neurotransmitter is excitatory or inhibitory depends on the type of receptor it binds to on the postsynaptic neuron. Excitatory neurotransmitters typically cause depolarization of the postsynaptic membrane, making it more likely that an action potential will occur, while inhibitory neurotransmitters typically cause hyperpolarization, making it less likely that an action potential will occur.
