1. 1 Fig. 3-3. Cell membrane. Look for proteins, phospholipids, and carbohydrates.

2. 2 Fig. 3-18. Simple diffusion.

3. 3 Fib. 3-19. Molecules can diffuse through the cell membrane.

4. 4 Osmosis How is osmosis like diffusion? How is osmosis not like diffusion?

5. 5 Filtration What force moves water by filtration?

6. 6 Carrier-mediated transport A carrier is something in the membrane that moves molecules through the membrane. What type of molecule would you expect to be a carrier?

7. 7 Fig. 3-22. Facilitated diffusion. What type of molecule facilitates the diffusion of the glucose through the cell membrane?

8. 8 Fig. 3-23. Active transport. What type of molecule in the membrane accomplishes this?

9. 9 Fig. 3-25. Receptor- mediated endocytosis is a form of bulk transport. What type of molecule is the “receptor”? What are the other forms of bulk transport?

10. 10 Fig. 3-26. Pinocytosis and phagocytosis. Where have we seen these processes before?

11. 11 Fig. 3-11. See how the lysosome is involved with the process of endocytosis. Is the endocytosis illustrated here called pinocytosis or phagocytosis?

12. 12 Fig. 3-10. Exocytosis. Notice the importance of the Golgi in this process.
