Question

Quizplus · Accepted Answer

The Na⁺/K⁺ ATPase is a key protein found in animal cells that pumps sodium ions out of the cell and potassium ions into the cell. This protein is critical for maintaining proper ion balance and pH within the cell. The gene variants that allow for the exchange of Na⁺ for K⁺ are only found in certain animal species, making the Na⁺/K⁺ ATPase unique to animals. It is not found in fungi or plants.
