3. $100 A: In this type of reaction, energy is released. (Combustion and Respiration can be classified as this type.)

4. $100 Q: What is exothermic? (Since the reaction is “downhill” overall, the products end up w/less energy and energy is released.)

5. $200 A: How do you calculate the calorie content of a snack food? (Hint: how do you calculate heat gained by water?)

6. $200 Q: What is H=m x C x Δ t?

7. $300 A: In this type of reaction the products have more PE than the reactants.

8. $300 Q: What is an endothermic reaction? (Since the products have more PE, energy had to be absorbed in this reaction, it’s “uphill” overall.)

9. $400 A: A: The reaction that would directly supply energy to a cell for cellular work. 1.ADP + P  ATP 2.C 6 H 12 O 6 + O 2  CO 2 + H 2 O 3.ATP  ADP + P 4.CO 2 + H 2 O  C 6 H 12 O 6 + O 2

10. $400 Q: What is Reaction 3? (ATP  ADP + P, the removal of a phosphate group releases energy)

11. $500 A: The pathway in aerobic respiration that transfers the most energy to ATP molecules.

12. $500 Q: What is the Electron Transport Chain?

13. $100 A: The 6-Carbon molecule that is the reactant that begins the series of reactions of this pathway.

14. $100 Q: What is glucose?

15. $200 A: The net yield of ATP from the reactions during glycolysis.

16. $200 Q: What is 2 ATP? http://www.supplementsuk.co.uk/gfx/cartoon_muscle.gif

17. $300 A: This end-product of glycolysis contains most of the PE that was originally in glucose.

18. $300 Q: What is pyruvic acid?

19. $400 A: If oxygen is not available to a cell, this pathway follows glycolysis.

20. $400 Q: What is fermentation?

21. $500 A: If oxygen is available to a cell, the end-product of glycolysis must first be converted to this molecule before the next pathway begins. Image from http://www.i-claudius.com/cartoons/scrapbook02.htmlhttp://www.i-claudius.com/cartoons/scrapbook02.html

22. $500 Q: What is acetyl-CoA?

23. $100 A: This molecule binds with acetyl-CoA to begin the Krebs cycle.

24. $100 Q: What is oxaloacetic acid?

25. $200 A: The yield of ATP molecules from two rounds of the Krebs cycle.

26. $200 Q: What is 2 ATP? (Remember, the Krebs cycle occurs 2x because 2 acetyl- CoA molecules are formed from the conversion of 2 pyruvic acid molecules.)

27. $300 A: These molecules are released from the cell following the complete breakdown of a glucose molecule that is completed during the Krebs cycle. (i.e.: these molecules contain the carbon atoms that were originally in glucose.)

28. $300 Q: What are carbon dioxide molecules?

29. $400 A: Since little ATP is formed during the Krebs cycle, most of the energy originally in glucose is transferred to molecules of _______ during the Krebs cycle.

30. $400 Q: What are molecules of NADH?

31. $500 A: The Krebs cycle is the first stage of this type of respiration.

32. $500 Q: What is aerobic respiration?

33. $100 A: The reactions of the ETC occur along the inner membrane of this organelle. http://www.sem.com/microsco/micrimag.htm

34. $100 Q: What is the mitochondrion?

35. $200 A: These macromolecules make up the ETC.

36. $200 Q: What are proteins?

37. $300 A: The energy from electrons moving down the ETC is used to pump these particles into the outer compartment.

38. $300 Q: What are hydrogen ions (protons)?

39. $400 A: The name of the specialized protein that uses energy from the diffusion of H+ to synthesize ATP.

40. $400 Q: What is ATP synthase?

42. $500 A: The yield of ATP from the ETC.

43. $500 Q: What is 34 ATP?

44. $100 A: Fermentation is also called anaeorobic respiration because it occurs if this molecule is not present.

45. $100 Q: What is oxygen?

46. $200 A: The number of ATP produced per glucose molecule if a cell is undergoing fermentation.

47. $200 A: What is 2 ATP (This is the number produced in glycolysis.)

48. $300 A: The location of fermentation in a cell.

49. $300 Q: What is the cytoplasm?

50. $400 A: Fermentation produces either ethyl alcohol or this molecule.

51. $400 Q: What is lactic acid?

52. $500 A: The reaction(s) following glycolysis during fermentation are important because, even though no more ATP is produced, the reaction(s) regenerates this molecule.

53. $500 Q: What is NAD+?

54. $100 A: The total number of ATP produced per glucose molecule during aerobic respiration.

55. $100 Q: What is 38?

56. $200 A: These organisms do both respiration and photosynthesis.

57. $200 Q: What are autotrophs?

58. $300 A: The type of cell in humans where fermentation would likely take place during strenuous exercise.

59. $300 Q: What is a muscle cell?

60. $400 A: Besides glucose, what is the other reactant of aerobic respiration (in the summary equation)?

61. $400 Q: What is oxygen?

62. $500 A: The two products of aerobic respiration (in the summary equation).

63. $500 Q: What are carbon dioxide and water?
