WebHow 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. WebSodium Potassium Pump Function The primary function of the sodium-potassium pump is to propel potassium ions inside the cell, and at the same time extract sodium ions from the cell. Due to this intricacy, the sodium-potassium pump is considered one of the most critical processes inside the body.

WebMay 25, 2024 · The sodium-potassium pump works by pumping two potassium ions into the cell and pumping out three sodium ions using the energy from an ATP molecule. This leads to a build-up of considerable differences in the concentration of the ions on the outside and inside of the cell.
