What happens to the resting membrane potential of -70 mV when channels for an anion with an equilibrium potential of -80 mV open?
A) membrane stabilization
B) hyperpolarization
C) repolarization
D) depolarization
E) returns to -70 mV

Question

Quizplus · Accepted Answer

When channels for an anion with an equilibrium potential of -80 mV open, the membrane potential will move towards the equilibrium potential of that anion, making the inside of the cell more negative than the resting membrane potential of -70 mV. This process is known as hyperpolarization.
