1. Cell Transport Quiz 11/5-11-6

2. You may not talk to anyone else, use anyone else’s paper, or your notes. Please sit quietly until everyone is done. When you are done, turn your paper over on your desk.

3. 1. What must be used in facilitated diffusion and active transport in order for molecules to go across the cell membrane? 2. What must be used to move a substance against its concentration gradient in active transport? 3. What is the difference between endo and exocytosis? Next slide

4. 4. Draw a picture to represent active transport 5. Draw a picture to represent passive transport. 6. Using the terms high concentration, describe how molecules move in active transport. 7. Using the terms high concentration and low concentration, describe how molecules move in simple diffusion and passive transport. Next slide

5. 8. Draw a cell in a solution. Label one side hypertonic and the other hypotonic. Show which way the water would move. 9. Do molecules quit moving across a membrane when it is at equilibrium? EXPLAIN end of quiz
