Protein structures on the postsynaptic neuron that have recognition sites on the extracellular side and G proteins on the intracellular side are known as
A) ionotropic receptors.
B) metabotropic receptors.
C) autoreceptors.
D) transporter molecules.

Question

Quizplus · Accepted Answer

Protein structures with recognition sites on the extracellular side and G proteins on the intracellular side are characteristics of metabotropic receptors. Ionotropic receptors are membrane ion channels that open upon binding with specific neurotransmitters, while autoreceptors are located on presynaptic neurons and regulate the release of neurotransmitters. Transporter molecules are proteins that move neurotransmitters back into the presynaptic neuron for reuptake.
