What is the name of the mechanism that ensures that there is a higher concen- tration of sodium ions in the extracellular fl uid than in the intracellular fl uid? A. Facilitated diffusion B. The sodium-potassium pump C. Secondary active transport D. Osmosis
Option B.The Na K -ATPase pump helps to preserve osmotic equilibrium and membrane viable in cells. The sodium and potassium cross towards the attention gradients. The Na K -ATPase pump keeps the gradient of a higher awareness of sodium extracellularly and a greater level of potassium intracellularly.
