Classical Neurotransmitters - Part 8

Classical neurotransmitters refer to a small group of small molecule neurotransmitters. These neurotransmitters are used by the nervous system in a variety of circuits to transmit information from pre-synaptic neurons to post-synaptic cells. Test your basic knowledge of classical neurotransmitters by taking this simple quiz.

(1) In GABAergic axon terminals, this membrane transport protein leads to the accumulation of GABA into synaptic vesicles:

	(A) Vesicular GABA transporter (VGAT)
	(B) Vesicular inhibitory amino acid transporter (VIAAT)
	(C) Na⁺/Cl⁻/GABA cotransporter

(2) Vesicular inhibitory amino acid transporter (VIAAT) transprts the following neurotransmitter(s) into synaptic vesicles of axon terminals.

	(A) Acetylcholine
	(B) Aspartate
	(C) γ-Aminobutyric acid (GABA)
	(D) Glutamate
	(E) Glycine

(3) A functional GABA_A receptor is composed of __________ subunits.

	(A) 1
	(B) 2
	(C) 3
	(D) 4
	(E) 5

(4) GABA_B receptors oligomerize to form a multimer composed of __________ subunits.

	(A) 1
	(B) 2
	(C) 3
	(D) 4
	(E) 5

(5) A functional GABA_C receptor is composed of __________ subunits.

	(A) 1
	(B) 2
	(C) 3
	(D) 4
	(E) 5
