Transport Across Cell Membranes

Questions to answer:

  1. How does the second law of thermodynamics allow for diffusion of substances?
  2. How is active transport possible, since it contradicts the tendencies of the second law of thermodynamics?  
  3. Diagram one complete cycle of the Sodium-Potassium pump.  Is this active or passive transport?
  4. Is it possible for a solution to be both hypertonic and hypotonic?  Why or Why not?
  5. How do large molecules get taken in to or removed from the cell?
