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. 11 Nov 2016
