The "undershoot" phase of hyperpolarization is due to ________.
A) slow opening of voltage-gated sodium channels
B) sustained opening of voltage-gated potassium channels
C) rapid opening of voltage-gated calcium channels
D) slow restorative actions of the sodium-potassium ATPase

Question

Quizplus · Accepted Answer

The undershoot phase of hyperpolarization is due to sustained opening of voltage-gated potassium channels. This allows for an efflux of potassium ions, leading to a more negative membrane potential.
