Question

Quizplus · Accepted Answer

If the sodium-potassium pumps fail to function, the extracellular concentration of potassium ions will increase, and the intracellular concentration of sodium ions will increase. This will lead to the membrane potential becoming more positive than normal, ultimately disrupting the cell's ability to generate and propagate action potentials.
