## hpfan101 one year ago How does the sodium-potassium pump work: How many sodium ions are pumped across the membrane during each cycle? How many potassium ions are pumped across the membrane during each cycle? Are the ions moving from high to low concentration or from low to high concentration? What does the pump use for energy to move the ions?

$$The~ Sodium-Potassium ~Pump.$$ 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.
