Which of the following describes the cause of the undershoot phase of hyperpolarization?

B) the sustained opening of voltage-gated potassium channels
C) the rapid opening of voltage-gated calcium channels
D) the slow restorative actions of the sodium-potassium ATPase

Question

Quizplus · Accepted Answer

The undershoot phase of hyperpolarization is primarily due to the sustained opening of voltage-gated potassium channels, allowing potassium ions to exit the neuron, making the inside of the cell more negative than the resting potential.
