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

Question

Quizplus · Accepted Answer

Voltage-gated channels open and close in response to changes in membrane potential and play a crucial role in the generation and conduction of action potentials. Mechanically gated channels open in response to physical forces, such as pressure or stretch; leakage channels are always open and allow the passive movement of ions down their concentration gradient; and ligand-gated channels open in response to the binding of a specific ligand or neurotransmitter.
