Receptors for the inhibitory neurotransmitters GABA and glycine:

Question

Quizplus · Accepted Answer

Receptors for the inhibitory neurotransmitters GABA and glycine are ligand-gated anion channels, which allow the influx of negatively charged ions such as chloride (Cl-) into the cell. This leads to hyperpolarization of neuronal cell membranes, making it more difficult for the cell to generate an action potential and transmit signals. Therefore, both options A and C are correct. Option B is not correct because ligand-gated cation channels would allow positively charged ions such as sodium (Na+) or calcium (Ca2+) into the cell, which would depolarize the membrane and promote the generation of action potentials.
