Physiology Test Question

Pre-synaptic GABA_B receptors are:

	(A) Ligand-gated chloride (Cl⁻) channels
	(B) G protein-coupled receptors that, once activated, reduce the activity of potassium (K⁺) channels in the plasma membrane (i.e., decrease in membrane K⁺ conductance).
	(C) G protein-coupled receptors that, once activated, increase the activity of potassium (K⁺) channels in the plasma membrane (i.e., increase in membrane K⁺ conductance).
	(D) G protein-coupled receptors that, once activated, reduce the activity of calcium (Ca²⁺) channels in the plasma membrane (i.e., decrease in membrane Ca²⁺ conductance).
	(E) G protein-coupled receptors that, once activated, increase the activity of calcium (Ca²⁺) channels in the plasma membrane (i.e., increase in membrane Ca²⁺ conductance).
