Sagot :
The sodium-potassium pump continually removes three sodium ions from the cell for every two potassium ions it introduces. Thus, it preserves the significant potassium ion gradient across the membrane, which served as the foundation for the resting membrane potential.
What is the role of sodium-potassium pump?
The sodium-potassium pump is a protein that has been found in many cells and is responsible for keeping the internal concentration of sodium ions [Na+] lower than that of the surrounding medium (blood, body fluid, or water) and the internal concentration of potassium ions [K+] higher than that of the surrounding medium (blood, body fluid, or water). The adenosine-triphosphatase (ATPase)-active pump moves across the cell membrane and is triggered by both internal [Na+] and external [K+].
This enzyme pumps K+ inward and Na+ outward using metabolic energy. The steady state differential in Na+ and K+ concentrations maintained by the pump is essential for maintaining the resting potential of cells and associated bioelectric phenomena like the action potential. There have also been discovered additional ion pumps that transfer various ions.
