Cell Signaling: How Your Cells Talk To Each Other

WebbThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane ( Figure 3.8) 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.
