Across
  1. 2. / In a hypertonic environment, plant cells lose water and eventually, the membrane pulls away from the wall, and the cell may die.
  2. 6. / The diffusion of water through a selectively permeable membrane.
  3. 9. / a sugar chain often found interacting with the cell membrane
  4. 13. / these fats can have one or more double bonds.
  5. 14. / First letter of the two words that describe one of the six major functions of membrane proteins.
  6. 16. / a disease in which the LDL might have had a receptor mutation.
  7. 19. First letter of the two words that describe one of the six major functions of membrane proteins.
  8. 21. / proteins that are bound to the surface of the membrane.
  9. 22. / the end of a transmembrane protein that faces the extracellular side of the cell.
  10. 23. / these fats have only single bonds.
  11. 28. / A nonpolar molecule, such as hydrocarbons, that can dissolve in the lipid bilayer and pass through the membrane rapidly.
  12. 31. / First two letters of the six major functions of membrane proteins
  13. 32. / First letter of the three words that describe one of the six major functions of membrane proteins.
  14. 33. / Proteins used for facilitated diffusion of water.
  15. 34. / A solution in which the solute concentration is less than that inside the cell.
  16. 36. / A solution in which the solute concentration is greater than that inside the cell.
  17. 37. / First two letters of the word that describes how the membrane is linked to the extracellular matric (ECM) and is one of the six major functions of membrane proteins.
Down
  1. 1. / A type of diffusion where the plasma membrane “helps” particles pass through protein channels, and no energy is used.
  2. 3. / A type of molecule, such as sugars, that do not cross the membrane easily.
  3. 4. T kind of molecule that contains hydrophobic and hydrophilic regions.
  4. 5. / the end of a transmembrane protein that faces the cytoplasmic side of the cell.
  5. 7. / The ability of a surrounding solution to cause a cell to gain or lose water.
  6. 8. / Any molecule that binds specifically to a receptor site of another molecule.
  7. 10. /
  8. 11. / The most abundant macromolecule in the plasma membrane.
  9. 12. / A solution in which the solute concentration is the same as that inside the cell; no net water movement across the plasma membrane occur.
  10. 15. / a lipid that can be found within the animal cell membrane.
  11. 17. / First letter of the two words that describe one of the six major functions of membrane proteins.
  12. 18. / Channels that open or close in response to a stimulus (gated channels).
  13. 20. integral protein that span the membrane.
  14. 24. / A type of membrane transport that occurs when the plasma membrane uses energy to move particles against a concentration gradient; it needs transport proteins.
  15. 25. / Occurs when a plant cell in a hypotonic solution swells until the wall opposes uptake of liquid.
  16. 26. / aminoacids of the hydrophobic regions of an integral protein, often coiled into alpha helices.
  17. 27. / If a plant cell and its surroundings are isotonic, there is no net movement of water into the cell and the plant may wilt.
  18. 29. / Movement of particles from an area of high to low concentration.
  19. 30. / Occurs when active transport of a solute indirectly drives transport of other solutes.
  20. 35. / proteins that penetrate the hydrophobic core.
