Structure and Function of Cell Membranes

Structure and Function of Cell Membranes

Structure and Function of Cell Membranes. Structure of Lipid Bilayer Made of lipid (fat) and protein molecules. The lipid bilayer forms the framework of the cell membrane. Protein molecules are embedded in the bilayer to allow substances to enter and exit the cell.
