Question

. After the action potential passes through an axon, what restores the resting potential?

A. Gated sodium channels open and allow sodium to flow into the cell.
B. Gated sodium channels open and allow potassium ions to flow out.
C. Gated potassium channels open and allow potassium ions to flow out.
D. Gated potassium channels open and allow sodium to flow out of the cell.

Answer 1

D. Gated potassium channels open and allow sodium to flow out of the cell.
To restore the resting potential, the potassium ion flows out by the gated potassium channel.
Hope this helps.
