WebSodium is the main cation in the ** body fluid outside the cells, such as blood and interstitial fluid (extracellular), and **potassium is the main cation in the body cells (intracellular). Cell membranes contain sodium-potassium pumps that regulate the balance of sodium and potassium intra- and extra- cellularly. WebFirst, the pump binds ATP and three sodium ions from the cytoplasm. The ATP then phosphorylates the pump and it shifts in shape, creating an opening towards the outside of the cell. The sodium is released and two …
