Proteins of the membrane that usually are exposed to both exterior and interior environment that transports molecules into and out of cell.
What are/ what do peripheral proteins do?

Extra Cellular Matrix (ECM)
Fluid Mosaic Model
A model that states that the membrane is a fluid structure with a Mosaic of various imbedded proteins.
What does Cholesterol do?
Cholesterol prevents the plasma membrane from becoming too fluid at high temperatures and too solid at lower temperatures.
Glycoproteins and glycolipids
