3. Phospholipid Membrane component

4. Proteins of the Membrane

5. Integral and Peripheral proteins

6. Membrane Protein functions

7. Cholesterol of the Membrane

8. Fluid – Mosaic Model

10. Cell – to – Cell Recognition Cells need to communicate
Cell – to – Cell Recognition Cells need to communicate. Can you see the green cell “hands”?

11. Know this! Cell Membrane: Composed of phospholipid bilayer
Hydrophilic heads on outside
Hydrophilic tails on inside
Proteins embedded for transport and communication
-cholesterol for structure and keeping membrane fluid
Glycoproteins identify surrounding molecules and cells
