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

Question

Quizplus · Accepted Answer

When channels for a cation with an equilibrium potential of -80 mV open, the membrane potential will move towards -80 mV, causing hyperpolarization from the original -70 mV.
