GABA and Glycine Activate Ionotropic Channels That Conduct Chloride

question 6

Multiple Choice

GABA and glycine activate ionotropic channels that conduct chloride. How does the chloride conductance inhibit excitation? Select all that apply.

• A) It lowers the voltage across the membrane to below action potential threshold.
• B) It blocks activation of the excitatory receptor.
• C) It provides an increased resistance in the membrane, making it more difficult to depolarize the voltage across the membrane.
• D) It provides increased conductance in the membrane, making it more difficult to depolarize the voltage across the membrane.
