What happens to the resting membrane potential of -70 mV when potassium channels close?
A) hyperpolarization
B) membrane stabilization
C) returns to -70 mV
D) depolarization
E) repolarization

Question

Quizplus · Accepted Answer

When potassium channels close, potassium ions cannot exit the cell as easily, leading to a buildup of positive charges inside the cell. This reduces the negative charge inside the cell relative to the outside, causing depolarization.
