4. Proteins are made of these molecules.

5. What are amino acids?

6. These molecules speed up a reaction by lowering the activation energy.

7. What is an enzyme?

8. A change in pH or temperature does this to an enzyme.

9. What changes the shape or denatures the enzyme so it no longer works?

10. A polypeptide chain is a protein that is held together by _____ bonds.

11. What are peptide bonds (a type of covalent bond)

12. The lock and key model. Explain how enzymes work using either the liver lab or the puffN lab. Make a diagram of the lock and key model.

13. What is a model in which the enzyme has a specific shape that fits a matching substrate.?

14. Glucose is this type of carbohydrate.

15. What is a monosaccharide?

16. Starch and glycogen store glucose and are this type of carbohydrate.

17. What is a polysaccharide?

18. This is why animals in cold climates store their extra energy as lipids (fats).

19. What is to insulate their bodies?

20. These lipids make up the majority of a cells membrane.

21. What are phospholipids?

22. Lipids are not good solvents.

23. What is a non-polar molecule?

24. A lot of energy has to be absorbed before water’s temperature changes because of this property of water.

25. What is a high specific heat?

26. The following diagram shows water in this state of matter.

27. What is solid?

28. Molecules of water are moving too fast to form hydrogen bonds so exist in this state of matter.

29. What is a gas?

30. Properties (name 2) of water that result from water being a polar molecule.

31. What are good solvent, high surface tension or expands when freezes?

32. Water is necessary for all life. This is because of water’s unique properties. Explain at least two properties and how they are important to life.

33. What are 1. Good solvent – dissolves chemicals necessary for life. 2. High specific heat – keeps Earth’s temperature stable and body temperatures stable 3. Expands when freezes – important for life under water?

34. This type of bond shares electrons.

35. What is a covalent bond?

36. Two atoms of opposite charge are held together by electrical attraction (a type of bond).

37. What is an ionic bond?

38. Draw an atom of carbon, showing protons neutrons and electrons.

40. Helium and other nobel gases never react.

41. What is because they have a full outer shell of electrons?

42. All organic molecules have this element in it.

43. What is carbon?

44. The 4 elements that make up 96% of life.

45. What are carbon, hydrogen, oxygen and nitrogen?

46. A pH of 2 is ____ times more acidic then a pH of 7.

47. What is 100,000?

48. An acid has more____ ions.

49. What are hydrogen ions?

50. pH of 9.

51. What is basic (or alkaline)?

52. These substances neutralize acids and bases.

53. What are buffers?

54. Consider the following.. The pH Scale. What acid rain is and it’s impact on life. Why buffers are important in living systems. How enzymes work and WHY they are important to living systems. Why water is SO important to living systems.
