● Cell Transport Prezi Topic Presentation: click here Supplementary Resources: “Crash Course: Biology” Videos: In Da Club - Membranes & Transport: Biology #5 Videos By Paul Anderson: “Cell Membranes” “Transport Across Cell Membranes” Questions to answer: 1. How does the second law of thermodynamics allow for diffusion of substances? 2. Explain the major difference between simple diffusion and facilitated diffusion. 3. How is active transport possible, since it contradicts the tendencies of the second law of thermodynamics? 4. Where does the energy to power active transport come from? 5. Diagram one complete cycle of the Sodium-Potassium pump. Is this active or passive transport? 6. What is osmosis? What is tonicity? 7. Explain the meaning of the statement: “Tonicity is only useful as a comparative term.” 8. Is it possible for a solution to be both hypertonic and hypotonic? Why or Why not? 9. Why do animal cells prefer to be in isotonic solutions, while plant cells prefer to be in hypotonic solutions? 10. How does a paramecium deal with its hypotonic environment? 11. How do large molecules get taken into the cell?
