Question

Quizplus · Accepted Answer

Ionotropic receptors are ligand-gated ion channels, meaning that they open in response to a specific neurotransmitter binding to the receptor. This allows ions to flow through the channel, resulting in a rapid change in the membrane potential of the postsynaptic neuron.
