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

Question

Quizplus · Accepted Answer

Inhibitory neurotransmitters are expected to hyperpolarize the membrane, making it more difficult for an action potential to occur. This is typically done by opening chloride channels or potassium channels, allowing negatively charged ions to enter the cell or positively charged ions to exit the cell, respectively. This creates a more negative charge in the cell, making it less likely for an action potential to fire.
