An additional critical group of integral proteins are mobile recognition proteins, which serve to mark a mobile’s identity in order that it may be acknowledged by other cells. A receptor is a sort of recognition protein that can selectively bind a particular molecule outside the house the cell, and this binding induces a chemical reaction inside the mobile. A ligand is the specific molecule that binds to and activates a receptor.
