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.
