Bio141 F Problem Set III Lipids, Membrane transport, and Cell structure 1 Note: Supplemental Instruction Problem Sets provide you a means to test your ability to apply your knowledge to biological questions. It is highly suggested that you work on these on your own, but they do not have to be handed in and will not be graded. Your TAs will hold Supplemental Instruction sessions every week for discussion of the topics in these sets, but neither they or your professor will provide you with the answers. Lipids and Membrane Transport Go to this website to visualize the interactions between different types of phospholipids in a membrane: http://telstar.ote.cmu.edu/biology/MembranePage/index2.html http://telstar.ote.cmu.edu/biology/lab/modbio/Permeability.html 1. When biomedical researchers design drugs that must enter cells to be effective, they sometimes add different groups to make the drug molecules more likely to pass through plasma membranes. What kind of chemical group would you choose to add to your drug? 2. Responding to their environment, plants alter the permeability of their phospholipid bilayer by incorporating different percentage of different components. Cold
