Campbell’s Biology,
7th Edition Created by: C. Massengale, Stuttgart School District Chapter Outline:
Chapter Objectives:
Membrane Structure
1. Explain why phospholipids are amphipathic
molecules.
2. Explain what freeze-fracture techniques
reveal about the arrangement of proteins in membranes.
3. Describe the fluidity of the components of a
cell membrane and explain how membrane fluidity is influenced by temperature
and membrane composition.
4. Explain how cholesterol resists changes in
membrane fluidity with temperature change.
Traffic Across Membranes
5. Distinguish between peripheral and integral
membrane proteins.
6. List six major functions of membrane proteins.
7. Explain the role of membrane carbohydrates in
cell-cell recognition.
8. Explain how hydrophobic molecules cross cell
membranes.
9. Distinguish between channel proteins and
carrier proteins.
10. Define diffusion. Explain why diffusion is a spontaneous
process.
11. Explain why a concentration gradient of a substance
across a membrane represents potential energy.
12. Distinguish among hypertonic, hypotonic, and isotonic
solutions.
13. Define osmosis and predict the direction of water
movement based on differences in solute concentrations.
14. Describe how living cells with and without cell walls
regulate water balance.
15. Explain how transport proteins facilitate diffusion.
16. Distinguish among osmosis, facilitated diffusion, and
active transport.
17. Describe the two forces that combine to produce an
electrochemical gradient.
18. Explain how an electrogenic pump creates voltage across
a membrane.
19. Describe the process of cotransport.
20. Explain how large molecules are transported across a
cell membrane.
21. Distinguish between
pinocytosis and receptor-mediated endocytosis.
