Chapter 4: Membrane Structure and Function

1. Describe the components of a cell membrane (Fluid--Mosaic Model) and each of their specific functions.

2. Differentiate between: integral vs. peripheral proteins, glycolipids vs. glycoproteins, heads vs. tails of phospholipids, passive vs. active transport, diffusion vs. osmosis and solute vs. solvent

3. Differentiate between the roles of the following proteins and any related complications: a. Channel proteins b. Carrier proteins c. Cell Recognition proteins d. Receptor proteins e. Enzymatic proteins

4. What items can pass through a phospholipid bilayer? Why? 5. What can impact the rate of diffusion? 6. Comparing solute and solvent concentrations: differentiate between hypertonic, hypotonic and

isotonic solutions. 7. What is osmotic pressure? 8. Define/describe the following: cytolysis, turgor pressure, crenation and plasmolysis 9. If you put a blood cell in a very salty solution describe the outcome using appropriate terms from
