MOST IMPORTANT INFO:

1. REVIEW THE MOLECULAR STRUCTURE. 

   • Make sure that you can identify all the molecules shown on these figures:  4.2, 4.3, 4.4. 4.5, 4.7, 4.8, 4.9 

   • Review the characteristics of phospholipids; why are the hydrophilic "heads" such a big deal?   Why is cholesterol there?   

   • Proteins are important again.  

     • Why are enzymes in membranes?  What are their functions?  

     • Be able to list some functions of the other membrane proteins.  

     • In which proteins are the structures critical to their functions?  What do we mean by primary, secondary, tertiary, quartenary structure?  

     • This type of question is still VERY important:  
       mutations affecting shape of receptor proteins: 
       New cause identified for incurable muscle condition
       Define mutation in terms of DNA, primary structure and quartenary structure of protein, function. Be able to diagram (rough cartoons) of this mutant receptor and compare with a normal receptor.
