2. Organelle where ATP is produced

3. What is mitochondria

4. Organelle that contains enzymes to break down old molecules

5. What is a lysosome

6. Proteins are made here

7. What are ribosomes

8. The packaging the distribution center of the cell

9. What is golgi apparatus

10. Large membrane- bound storage space for water, waste products or food

11. What is a vacuole

12. The cell membrane is ______, which allows only certain things to come in and out of the cell

13. What is semi-permeable

14. Name 3 functions of membrane proteins

15. What is transport, cell adhesion, cell identity, receptor, channels

16. These molecules are embedded in the membrane and can act as channels for certain substances to pass into the cell

17. What are membrane proteins

18. The cell membrane is made of a bilayer of _____ that have a hydrophilic head and hydrophobic tail

19. What are phospholipids

20. The membrane will allow these molecules to pass directly through the bilayer

21. What is small, non-polar molecules

22. The movement of water across a membrane from high concentration to low concentration

23. What is osmosis

24. As a result of diffusion and osmosis, the tonicity of the system becomes

25. What is isotonic (it reaches equilibrium)

26. What would happen to a cell placed in a hypotonic environment?

27. What is the cell would swell (water will move into the cell)

28. Osmosis and diffusion require no energy because

29. What is it is moving from an area of high concentration to low concentration

30. When a cell is in an isotonic environment, are the solutes still moving across the membrane? If so, how?

31. Yes, they are moving back and forth equally

32. The movement of particles across the membrane against the concentration gradient

33. What is active transport

34. The movement of solutes down the concentration gradient with the aid of a transport protein

35. What is facilitated diffusion

36. These molecules would have to move through the membrane by facilitated diffusion because they cannot pass directly through the bilayer

37. What are polar molecules

38. A cell can get rid of very large molecules through

39. What is exocytosis

40. Can be thought of as “cell eating”

41. What is phagocytosis

42. The cell theory basically states that

43. What is all living things are made of cells, cells are the basic unit of life, and cells come from other cells

44. The process of taking large particles into the cell by means of infoldings, or pockets, of the cell membrane

45. What is Endocytosis

46. The phospholipid bilayer is called amphipathic because

47. What is has both polar (heads) and nonpolar (tails) components

48. The meshlike network of protein fibers that support the shape of the cell

49. What is the cytoskeleton

50. Trace the pathway of a protein from first being made to being broken down after use

51. The DNA in the nucleus gives the instructions for how to make the protein. That message is taken to the ribosome where the protein is assembled. The protein then makes its way through the endoplasmic reticulum where it is modified and then taken to the golgi apparatus where it is packaged and sent to where it needs to be. After it is used, the protein can be broken down by a lysosome.
