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

Question

Quizplus · Accepted Answer

When potassium channels open, potassium ions move out of the cell, making the inside of the cell more negative compared to the outside. This movement increases the polarity of the membrane, leading to hyperpolarization.
