question: gaba-a receptors are an example of which type of ion channel?

• voltage-gated
• ligand-gated
• mechanosensitive
• leak

Explanation:

GABA - A receptors open when the neurotransmitter GABA (a ligand) binds to them. Ligand - gated ion channels are activated by the binding of a chemical ligand (like a neurotransmitter). Voltage - gated channels open in response to voltage changes, mechanosensitive to mechanical stimuli, and leak channels are always open (or have a constant leak). So GABA - A receptors are ligand - gated.

Answer:

B. Ligand - gated
