Neurotransmitters categorized as inhibitory are expected to
A) close potassium channels.
B) close chloride channels.
C) act independently of their receptor proteins.
D) open sodium channels.
E) hyperpolarize the membrane.

Question

Quizplus · Accepted Answer

Inhibitory neurotransmitters typically function by hyperpolarizing the membrane, making it more negative and less likely to fire an action potential. This is often achieved through mechanisms such as opening potassium channels (allowing K+ to exit the cell, making the inside more negative) or opening chloride channels (allowing Cl- to enter the cell, making the inside more negative), rather than closing them.
