If the sodium-potassium pumps in the plasma membrane fail to function, the extracellular concentration of potassium ions will increase (A), the intracellular concentration of sodium ions will increase (B), the membrane will lose its capacity to generate action potentials (C), and the inside of the membrane will have a resting potential that is more positive than normal (D). Therefore, all of the above statements are true.
