7. Answer 3: Only the Light Dependent Reactions require the sunlight to occur.

8. Question 4: Where do the Light Dependent Reactions take place?

9. Answer 4 The LDR takes place in the thylakoids of the chloroplasts.

10. Question 5: What is the most important photosynthetic pigment?

11. Answer 5 Chlorophyll is the most important pigment found in plants

12. Question 6 What color is chlorophyll and why?

13. Answer 6: Chlorophyll is green because when white light (all the colors of the rainbow) shines on the plant, the chlorophyll absorbs all colors, but reflects the green wavelength.

14. Question 7: What gets broken down in the LDR? What does it get broken down into?

15. Answer 7: Water gets broken down in the LDR into oxygen, hydrogen ions and electrons

16. Question 8: What happens to each of the products produced from the splitting of water? Hydrogen ions? Electrons? Oxygen?

17. Answer 8: The hydrogen ions build up and then travel through the protein channel to help produce ATP. Some hydrogen ions attach to NADP+ becoming NADPH. The electrons refuel those that were lost to the ETC The oxygen is given off as a waste product and is released through the stomata.

18. Question 9 Is the following anabolic or catabolic? How do you know? ATP  ADP + P + E

19. Answer 9: Catabolic because bonds are being broken and energy is released.

20. Question 10: What are the products of the LDR of photosynthesis?

21. Answer 10: Oxygen NADPH ATP

22. Question 11 Which of the following are used in the overall reaction for photosynthesis? A. Carbon Dioxide B. Water C. Light D. All of the above

23. Answer 11: D- All of the above

24. Question 12: Where does the Calvin Cycle take place?

25. Answer 12: The Calvin Cycle takes place in the stroma of the chloroplast

26. Question 13: What will happen to the rate of photosynthesis if the light intensity decreases?

27. Answer 13 The rate will decrease if the light intensity decreases.

28. Question 14: Some bacteria, algae and plants are all considered to be?

29. Answer 14: Autotrophs

30. Question 14: What are the reactants of the Calvin Cycle?

31. Answer 15 The Calvin Cycle needs: Carbon dioxide ATP NADPH

32. Question 16: Name the products of the Calvin Cycle

33. Answer 16: The Calvin Cycle produces: Glucose ADP +P NADP+

34. Question 17: Which of the following affects the rate of photosynthesis? A. water B. temperature C. light intensity D. all of the above

35. Answer 17: D. All of the above

36. Question 18: Where does the energy come from that fuels the light dependent reactions of photosynthesis?

37. Answer 18: The Sun

38. Question 19: Where does the energy come from that fuels the Calvin Cycle?

39. Answer 19: ATP and NADPH

40. Question 20: Label all of the following parts:

41. Answer 20: A. Adenine B. Ribose C. ADP D. ATP E. Adenosine

42. Question 21: Label the parts below:

43. Answer 21: 1. Thylakoid 2. Grana 3. Stroma

44. Question 22:  What is occurring at the arrow?

45. Answer 22: The electron transport chain

46. Question 23 At what number would you find water?

47. Answer 23 2

48. Question 24: What is the reaction that occurs at 5?

49. Answer 24 5= Calvin Cycle or Light Independent Reactions

50. Question 25: Where is the sun represented in this diagram?

51. Answer 25: 1

52. Question 26: What would Numbers 9 and 10 represent?

53. Answer 26: ATP and NADPH

54. Question 27: What is represented by number 6?

55. Answer 27: Oxygen

56. Question 28: What two wavelengths (colors) of light are most useful for photosynthesis?

57. Answer 28 Best= violet/blue 2 nd best=red

58. Question 29 How would you define the process of photosynthesis?

59. Answer 29: The process in which autotrophs use carbon dioxide and water and convert the energy of sunlight into chemical potential energy stored in glucose.

60. Question 30 Why would temperature affect the rate of photosynthesis?

61. Answer 30 The enzymes used in photosynthesis would not work as well if they were not at the optimal temperature.

62. Question 31 What is a pigment?

63. Answer 31 A substance that absorbs or reflects light

64. Question 32 True or false: During the Calvin Cycle, water gets split?

65. Answer 32 False- it occurs in the LDR

66. Question 33 What is the energy generated from the ETC used for?

67. Answer 33 To actively transport the hydrogen ions across the thylakoid membrane from a low concentration to a high concentration.

68. Question 34 What is happening at the indicated arrow?

69. Answer 34: Hydrogen ions are flowing through the ATP Synthase. As they flow through, it causes it to turn like a water wheel or turbine. This is a source of energy and that energy is used to put the P back onto ADP to form ATP.
