In this way, the motion of the Energetic transportation pump (the sodium-potassium pump) powers the passive transportation of sodium ions by creating a concentration gradient. When Energetic transportation powers the transport of another substance in this way, it is referred to as secondary active transport.

One more important team of integral proteins are cell recognition proteins, which serve to mark a mobile’s id in order that it might be recognized by other cells. A receptor is often a type of recognition protein which can selectively bind a particular molecule outside the house the mobile, which binding induces a chemical reaction inside the mobile. A ligand is the specific molecule that binds to and activates a receptor.
