I have a few questions: 1. What is the difference between secondary protein structures and tertiary protein structures? For secondary - I have interactions between amino acid and it depends on the R groups. And for Tertiary Structure - I have its a complex protein. Could you give me more specific interactions that happen at each level? 2. For clathrin dependent endocytosis when does clathrin bind to vesicle and when does it break off and get recycled? 3. Dr. Harris in class demonstrated osmosis with different concentrated solutions and added blood to each solution. I wanted to clarify what would happen to blood cells that were added to a solution that is 900M Nacl and 900 M urea ? Would these concentration equal out and become isotonic because urea can be absorb by blood cells? Or because of the high concentration of NaCl outside the cells membrane would the cell crenation?
