What is the sodium-potassium antiport exchange pump?

1 Answer

Sodium-Potassium pump is the process of moving sodium and potassium ions across the cell membrance.

Explanation:

The Sodium-Potassium pump is the process of moving sodium and potassium ions across the cell membrance. It is an active transport process utilising ATP gor necessary energy. It involves an enzyme referred to as Na+/K+-ATPase.
In order to move the ions (Na+ and K+) againts their gradients, energy is required. An ATP molecule inside the cell, binds to the pump transferring some energy to it.
ATPase enzyme pumps sodium is an antiporter-like activity but is not an antiporter bacause both molecules are moving against their concentration gradient. Thank.
