Sodium potassium pump is ,found on the plasma membrane in animal cells, it is involved in the active process of moving potassium and sodium ions across the cell membrane. The process involves hydrolysis of ATP to provide necessary energy. The process is responsible for maintaining the large excess of Na+ ions outside the cell and the large excess of K+ ions inside the cell. Therefore, failure of the sodium potassium pump can result to damage of the cell, cause swelling and rapturing of the cell as well this is due to unbalanced cellular charge across the membrane.
