C)Relative refractory period
D)Absolute refractory period
E)Repolarization

Question

Quizplus · Accepted Answer

Depolarization is the process by which the membrane potential becomes less negative (more positive) due to an influx of positively charged ions, such as sodium ions.

Answer: B 
 The action potential is an all-or-nothing electrical signal that occurs when the depolarization of a neuron reaches a certain threshold, resulting in the rapid opening of voltage-gated ion channels and the influx of even more positively charged ions.

Answer: E 
 Repolarization is the process by which the membrane potential returns to its resting state (more negative) after an action potential, typically due to the efflux of potassium ions.

Answer: C and D 
 The relative refractory period refers to the period of time after an action potential during which a neuron can still fire again, but only in response to a stronger-than-normal stimulus. The absolute refractory period refers to the period of time during which a neuron is incapable of firing another action potential, regardless of the strength of the stimulus.

Therefore, both C and D can be correct choices.
