Please answer ONE of the two questions below. If you answer both, I will only grade the first question answered. Please indicate which question you are answering. 1. Explain how the structure of the plasma membrane allows for it to be selectively permeable. How does the chemical structure of both integral and peripheral proteins predict their arrangement within the plasma membrane? 2. What are the three stages of cell signaling? Describe the cell-singaling processes that occur when the ligand is polar versus nonpolar.
