According to the Nernst Equation, Which Change Will Depolarize V_m

Question

According to the Nernst equation, which change will depolarize Vm, the membrane potential?
A) A decrease in temperature
B) An increase in the valence of the ion species involved
C) A decrease in the concentration of anions inside the membrane
D) A decrease in the electromotive force of the ion

Accepted Answer

A decrease in the concentration of anions inside the membrane will reduce the negative charge inside, leading to depolarization (a less negative membrane potential).
