WebWhy is it active transport? Because we're using ATP to drive sodium against its concentration gradient to keep pumping the sodium out of the cell, and then potassium kind of comes in, you could almost imagine, passively. It doesn't require ATP. And that's why this is often called a sodium-potassium ATPase, which means it's a protein or an ...
