### Plasma Membrane - Spans entire phospho membrane - **Crosier** lipid bilayer - **Peripheral** - don't have hydrophobic region - Not embedded in the bilayer - **Ratio of Lipids to Proteins** depends on plasma membrane - **Restrict Movement** of proteins by anchoring to cytoskeleton ### Carbohydrates - Associate with plasma membrane by binding to protein or lipid - Carbohydrate + lipid = glycolipid - Carbohydrate + Protein = glycoprotein. - Send signals between cells. - **Cell Recognition** - one cell binds to another cell. - Recognize eachother - Not permanent - **Cell Adhesion** - cells are held together - More permanent
