The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration.. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP.For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in.
The Sodium-Potassium Pump. The process of moving sodium and potassium ions across the cell membrance is an active transport process involving the hydrolysis of ATP to provide the necessary energy. It involves an enzyme referred to as Na + /K +-ATPase.
Best Answer: Na+/K+-ATPase (also known as the Na+/K+ pump or sodium-potassium pump) is an enzyme (EC 188.8.131.52) located in the plasma membrane (specifically an electrogenic transmembrane ATPase). It is found in the plasma membrane of virtually every human cell and is common to all cellular life. It helps maintain cell potential and regulate cellular volume.
What Is the Sodium-Potassium Pump? The sodium-potassium pump is an essential cellular membrane protein that functions by pumping out three sodium ions and taking in two potassium ions. This mechanism preserves the electrochemical gradient formed from the varying concentrations of sodium and potassium ions within the cell and its exterior.

The story of the sodium-potassium pump has strong ties to Denmark. In 1997, the Danish scientist Jens Chr. Skou received the Nobel Prize in Chemistry for his discovery, and over the years ...
The sodium-potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.
How does the sodium-glucose pump work? Put simply, the sodium-glucose pump describes the way cells use salt ions to absorb glucose. The process is powered in three ways: Electrical charges: Sodium is a positively-charged ion. Therefore, as the concentration of sodium builds up, an electric charge is created.
How a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
