Biology 1060 Chapter 7

1. Biology 1060Chapter 7 Membrane Structure and Function

2. Cell Membrane • Describe the properties of the cell membrane • Discuss how their contribute to its function • Describe the components of the cell membrane and their arrangements • Discuss the current model of cell membranes • Discuss each of the components and their relationship to fluidity

3. Membrane Proteins • Discuss the locations and functions of membrane proteins • Describe the mechanism by which membrane is acquired as secretion takes place

4. Selective Permeability • Describe why selective permeability is important • Give several examples of materials that cross • Discuss how hydrophobic and hydrophilic molecules are affected by the membrane • Describe the importance of transport proteins

5. Passive Transport • Define diffusion • Describe its mechanism and • Describe its importance to the cell • Define osmosis • Discuss its importance to the cell • Compare and contrast water balance in cells with and without cell walls

6. Passive Transport • Compare and contrast the reactions of cells in a/n • Hypotonic solution • Isotonic solution • Hypertonic solution • Evolution Connection p. 140

7. Facilitated Diffusion • Differentiate facilitated diffusion from simple diffusion • Describe the reason facilitated diffusion is important • Compare and contrast all mechanisms of transport across membranes

8. Active Transport • Describe why active transport is needed • Describe how active transport is accomplished • Describe the sodium-potassium pump and its effect on the cell • Describe how an electrogenic pump helps a cell • Discuss its transport • Scientific Inquiry p. 140

9. Bulk Transport • Discuss why bulk transport is necessary • Compare and contrast endocytosis and exocytosis • Compare the results associated with • Endocytosis • Phagocytosis • Pinocytosis • Receptor-mediated endocytosis • Science, Technology, and Society p. 140
