Which of the following is true of the action potential?
A) More sodium channels are opened at a lower voltage level than are the potassium channels.
B) The action potential requires 10 msec for completion.
C) The action potential requires the activity of the sodium-potassium transporters during the rising phase.
D) More potassium channels are opened at a lower voltage than are sodium channels.
E) The overshoot is due to a prolonged change in sodium conductance.

Question

Quizplus · Accepted Answer

The action potential involves the opening of sodium channels at a lower voltage threshold compared to potassium channels. This initial opening of sodium channels leads to the rapid depolarization phase of the action potential.
