Which ion channel opens in response to a change in membrane potential and participates in the generation and conduction of action potentials?
A) voltage-gated channel
B) ligand-gated channel
C) leakage channel
D) mechanically gated channel

Question

Quizplus · Accepted Answer

Voltage-gated channels open and close in response to changes in membrane potential and are critical for the generation and conduction of action potentials. Ligand-gated channels respond to the binding of a specific neurotransmitter or ligand, leakage channels are always open and allow ions to leak across the membrane, and mechanically-gated channels open in response to physical changes in the membrane, such as pressure or stretching.
