What Effect Would Decreasing the Concentration of Extracellular Potassium Ions

Multiple Choice

What effect would decreasing the concentration of extracellular potassium ions have on the resting membrane potential of a neuron?

A) The resting membrane potential would become more positive because more potassium ions would leave the cell through potassium leak channels.
B) The resting membrane potential would become more negative because more potassium ions would leave the cell through potassium leak channels.
C) The resting membrane potential would become more positive because more potassium ions would enter the cell through potassium leak channels.
D) The resting membrane potential would become more negative because more potassium ions would enter the cell through potassium leak channels.
E) The resting membrane potential would not change because it is controlled by the movement of sodium ions not potassium ions.
