1. Cell Membrane Maintains homeostasis by regulating the movement of molecules in and out of the cell

2. Fluid Mosaic Model Polar heads are orientated to the aqueous solution (inside and outside of cell) Non polar tails are orientated towards one another Integral proteins are embedded to form a mosaic

4. Membrane Proteins Channel Proteins (transport) Carrier Proteins (transport) Receptor Proteins (signal transduction) Cell Recognition Proteins (glycoprotein) Enzymatic Proteins Intercellular Joining Attachment for Cytoskeleton

6. Membrane Permeability Impermeable Permeable Differentially/Selectively Permeable

7. Terms to know Osmotic pressure Turgor Pressure Tonicity Isotonic Hypotonic Hypertonic Plasmolysis Creanation

8. Methods of Transport Across The Cell Membrane Passive Transport

10. Rate of Diffusion Temperature increase Increased concentration gradient Increased membrane permeability Smaller molecule size

11. Osmosis Diffusion of water through a semi permeable membrane

15. Facilitated Transport Movement of molecules along the concentration gradient with the aid of carrier proteins

17. Active Transport Movement of molecules against the concentration gradient using carrier proteins and ATP

19. Active Transport Endocytosis –Phagocytosis –Pinocytosis Exocytosis
