What will most affect the speed of an action potential?
A) The strength of the stimulus
B) The time since the last action potential
C) The length of the axon
D) The resistance of the membrane

Question

Quizplus · Accepted Answer

The resistance of the membrane will most affect the speed of an action potential as it determines how easily ions can pass through the membrane and contribute to the depolarization of the cell. Lower resistance means faster action potential propagation.
