The pump is now in its “open to the outside” shape. It loves potassium ions (K⁺). It grabs two potassium ions from outside.
A molecule of ATP comes along and donates a phosphate group (a tiny energy packet) to the pump. This energy changes the shape of the protein channel.
That’s like trying to push a crowd of people up an escalator going down. It requires energy . Embedded in the office wall is a special, revolving door. This isn’t just any door; it’s a protein channel called the Sodium-Potassium Pump .
