D) transporter molecules.

Question

Quizplus · Accepted Answer

Autoreceptors are protein structures located on the presynaptic neuron that monitor its activity level. They bind to neurotransmitters released by the presynaptic neuron and regulate the release of further neurotransmitters. Ionotropic and metabotropic receptors are postsynaptic receptors that bind to neurotransmitters and produce a response in the postsynaptic neuron. Transporter molecules are responsible for the reuptake of neurotransmitters back into the presynaptic neuron.
