Quizplus · Accepted Answer

The difference in ion concentration between the intracellular and extracellular fluids results from both active ion transport and passive diffusion of ions. Active ion transport is the movement of ions against their concentration gradient, which requires energy. Passive diffusion of ions is the movement of ions down their concentration gradient, which does not require energy.
