The difference between Integral Proteins and Peripheral Proteins
 * Integral Proteins || Also known as the intrinsic proteins are proteins which are found IN the cell membrane. These proteins are used for transporting important substances into the cells. There are different types of transporting methods, for different types of things to transport. ||
 * Peripheral Proteins || Are proteins that are most commonly found on the surface of the cell membrane. These proteins identify cells to the immune system to see what type of cell it is, and whether it is from a known or unknown source. ||

What are the key functions of a protein found embedded in the plasma membrane? To transport different important molecules into the cell The function of the cell membrane proteins
 * 1) To identify what type of cell it is, and if it is of their own kind. These proteins are sent by the immune system to check if any unknown cells are in the system. If there is such a cell, then the immune system will attack. If not, it gets to carry on with its happy life.
 * 2) Serves as receptors for the cell.
 * 3) Transports different iodine molecules into cell.
