Which would result from an increase in the extracellular concentration of K⁺ above normal? A) depolarization of resting nerve cells B) hyperpolarization of resting nerve cells C) The potassium equilibrium potential of nerve cells would become more negative. D) The sodium equilibrium potential would become less positive.

Question

Quizplus · Accepted Answer

An increase in extracellular K+ concentration reduces the gradient for K+ to leave the cell, causing depolarization of resting nerve cells.
