  1. What three classes can membrane proteins be grouped into?
  2. What are integral membrane proteins?


  3. What do most membrane spanning proteins use?
  4. What is Glycophorin A?
  5. What is bacteriorhodopsin?
  6. What are alpha-helices composed of?
  7. What is a hydropathy plot?
  8. What can multiple alpha-helices associate to form?


  9. What can proteins which do not span the membrane use alpha-helices for?
  10. How do porins span the cellular membrane?



  11. What can be seen in a Gram Negative bacteria cell wall?
  12. What are the general rules for transmembrane proteins
  13. How are membrane proteins distributed?
  14. How are proteins inserted into the membrane?
  15. What are lipid anchored proteins?
  16. What are peripheral membrane proteins?
  17. What has the best characterized plasma membrane?
  18. How can high purity preparations of cell membranes be obtained?
  19. How can membrane proteins be separated?
  20. What can staining reveal?
  21. What is Glycophorin?



    A Glycophorin is a sialoglycoprotein of the membrane of a red blood cell. It is a membrane-spanning protein and carries sugar molecules. It is heavily glycosylated (60%). Glycophorins are rich in sialic acid, which gives the red blood cells a very hydrophilic-charged coat. This enables them to circulate without adhering to other cells or vessel walls.
  22. What is spectrin?


    Spectrin is a cytoskeletal protein that lines the intracellular side of the plasma membrane in eukaryotic cells.
  23. What is Actin?
  24. What is the anion channel protein?
  25. What is Ankyrin?
