Question

GABA receptors play an essential role in neurotransmission in the central nervous system. In response to the appropriate signal, these receptors open up and allow Cl- to flow into the cell. Given this information, GABA receptors can be classified as a________

Answer 1

Answer:

GABAA receptors: Ligand-gated ion channel (also known as inotropic receptors)

Explanation:

The GABAA receptor is an inotropic receptor and ligand-gated ion channel; this GABAA receptor conducts CI- through its pore, which flows out of the cell if the internal voltage is less than resting potential and flows in if it is more than a resting potential (-75 mV). This causes an inhibitory effect on neurotransmission by diminishing the chance of a succesful action potential occurring.
