Question

Quizplus · Accepted Answer

Ionotropic receptors are protein structures on the postsynaptic neuron that have recognition sites located on the channel protein. When a neurotransmitter binds to these receptors, they directly open or close ion channels, leading to a rapid change in the membrane potential of the neuron. Metabotropic receptors, on the other hand, do not have ion channels but instead use a set of intracellular signaling pathways to change the activity of the neuron. Autoreceptors are receptors located on presynaptic neurons that regulate the release of neurotransmitters. Transporter molecules are proteins that are responsible for the reuptake of neurotransmitters from the synaptic cleft back into the presynaptic neuron.
