Here’s a clear and informative text on a classic example of : Example of Primary Active Transport: The Sodium-Potassium Pump (Na⁺/K⁺ ATPase)
One of the most well-studied and essential examples of primary active transport is the (Na⁺/K⁺ ATPase). Found in the plasma membranes of nearly all animal cells, this pump directly uses energy from adenosine triphosphate (ATP) to move ions against their concentration gradients. primary active transport example
