The brief period in which it is more difficult to launch a new action potential is called the __________.
A) action potential
B) depolarization period
C) ion channel
D) refractory period

Question

Quizplus · Accepted Answer

The refractory period is the brief period after an action potential during which it is more difficult to launch a new action potential, as the voltage-gated sodium channels are temporarily inactivated. This helps to ensure that the action potential travels in one direction and prevents continuous signaling. choices A, B, and C are not correct as they do not describe the refractory period.
