A graded hyperpolarization of a membrane can be induced by
A) increasing its membrane's permeability to Na+.
B) decreasing its membrane's permeability to H+.
C) decreasing its membrane's permeability to Cl-.
D) increasing its membrane's permeability to Ca2+.
E) increasing its membrane's permeability to K+.

Question

Quizplus · Accepted Answer

Increasing the membrane's permeability to K+ would result in a graded hyperpolarization, as K+ ions would move out of the cell, making the membrane potential more negative. The other choices would either have no effect on the resting membrane potential or would result in depolarization.
