Voltage-Gated Sodium Channels Have Both an Activation Gate and A(n)

Question

Voltage-gated sodium channels have both an activation gate and a(n) ________ gate.
A) inactivation
B) ion
C) swinging
D) repolarization
E) threshold

Accepted Answer

Voltage-gated sodium channels have both an activation gate and an inactivation gate. The activation gate opens in response to depolarization, allowing sodium ions to flow into the cell. The inactivation gate then closes to stop the sodium flow, ensuring that the channel does not stay open indefinitely.
