Chapter Six: Cell Membranes, Transport and Communication Outline and Review Questions Outline: 1. Membranes a. Structure b. Function 2. Transport a. Diffusion b. Osmosis c. Facilitated Diffusion d. Active Transport 3. Endocytosis and Exocytosis 4. Signal Transduction Review Questions: 1. What is the structure of the plasma membrane? What do we mean when we say that it is a fluid mosaic? 2. What are integral and peripheral proteins? 3. What are the functions of the plasma membrane? 4. When we say that the plasma membrane is selectively permeable, what do we mean? What molecules will easily pass through the membrane and what molecules will need help? 5. What is a concentration gradient? 6. What is diffusion?

Unformatted text preview: What energy is required for this process? 7. What is facilitated diffusion? What requirements are there for this process? 8. What is osmosis? 9. What is tonicity? What does hypertonic mean? Hypotonic? Isotonic? 10. Using these terms, you should be able to determine the tonicity of two solutions and be able to predict which way water will move, which way solute will move, and the potential outcome for a cell. 11. What is active transport? What requirements are there for this process? 12. What are exocytosis and endocytosis? Can you think of examples of each of these processes? 13. What is signal transduction? Why is this process important to the cell?...
