WebJan 3, 2024 · The Na + /K + pump is an active transport protein complex linked to ATPase activity. Next, we consider ion flow during cell excitation and how ion pumps work. Let’s begin by looking at the allosteric changes that occur when the Na+ /K+ pump works to restore and maintain ion gradients (illustrated on the next page). WebNerve Signals. The cell expends lots of energy in pumping sodium ions to the outside of the cell and pumping potassium ions to the inside of the cell. There is some diffusion of both ions across the cell membrane to the side where the concentration of each ion is less. Since the potassium ion leaks more easily, there is a slight elevation of ...
