WebbThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment.A phospholipid is a lipid molecule composed of two fatty acid chains, a glycerol backbone, and a phosphate group. WebbCell membranes (i.e., plasma membranes) consist of phospholipids and proteins (Figure 37.2).The fluid and dynamic phospholipid bilayer, with polar head groups on the intracellular and extracellular surfaces and fatty acid chains filling the inner space, acts as a permeability barrier to water-soluble molecules.
