Resting membrane potential is maintained by the sodium-potassium ion pump,or Na⁺/K⁺ATPase,which brings: A)two potassium ions into the cytosol and two sodium ions into the extracellular fluid. B)three potassium ions into the cytosol and three sodium ions into the extracellular fluid. C)two potassium ions into the cytosol and three sodium ions into the extracellular fluid. D)three potassium ions into the cytosol and two sodium ions into the extracellular fluid.

Question

Quizplus · Accepted Answer

The sodium-potassium pump (Na+/K+ ATPase) moves two potassium ions into the cytosol and three sodium ions into the extracellular fluid, using ATP to maintain the resting membrane potential.
