Question

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

Explanation:

Voltage - gated channels open in response to changes in membrane potential. They play a crucial role in the generation and conduction of action potentials. Ligand - gated channels open in response to ligands (chemical messengers). Leakage channels are always open and are involved in maintaining the resting membrane potential. Mechanically - gated channels open in response to mechanical stimuli.

Answer:

A. voltage - gated channel
