  1. Cells and Energy!

  2. Question 1 - 10 • What is the difference between ATP and ADP?

  3. Answer 1 – 10 • ATP has 3 phosphates while ADP only has 2 • ATP carries useable energy and ADP does not

  4. Question 1 - 20 • What organelle is primarily responsible for producing ATP if oxygen is present?

  5. Answer 1 – 20 • Mitochondria

  6. Question 1 - 30 • What is the name of the process by which some organisms use chemical energy instead of light to make energy-storing carbon-based molecules?

  7. Answer 1 – 30 • Chemosynthesis

  8. Question 1 - 40 • How many ATP are made in each of the following stages of Cellular Respiration: • Glycolysis • Krebs Cycle • Electron Transport

  9. Answer 1 – 40 • Glycolysis – net of 2 • Krebs Cycle – 2 • Electron Transport – usually 32, but in some organisms like protists, it is 34

  10. Question 1 - 50 • What stage of photosynthesis produces ATP?

  11. Answer 1 – 50 • Light-Dependent Reactions

  12. Question 2 - 10 • Within the Chloroplast, name the specific location of: • 1.Light-Dependent Reactions • 2.Light-Independent Reactions

  13. Answer 2 – 10 • Light-Dependent – Thylakoid • Light-Independent - Stroma

  14. Question 2 - 20 • What 2 energy storing molecules are created during the Light-Dependent Reactions?

  15. Answer 2 – 20 • NADPH • ATP

  16. Question 2 - 30 • What type of molecules are split during Photosystem 2 that gives of electrons, hydrogen ions, and oxygen?

  17. Answer 2 – 30 • Water

  18. Question 2 - 40 • What gas is needed during the Calvin cycle to produce Glucose?

  19. Answer 2 – 40 • Carbon Dioxide

  20. Question 2 - 50 • Name the products of photosynthesis

  21. Answer 2 – 50 • Glucose • Oxygen

  22. Question 3 - 10 What are the products of Glycolysis?

  23. Answer 3 – 10 • ATP • NADH • Pyruvate

  24. Question 3 - 20 • What are the products of the Krebs Cycle?

  25. Answer 3 – 20 • ATP • NADH • FADH2

  26. Question 3 - 30 • Name the two stages of Cellular Respiration that REQUIRE oxygen

  27. Answer 3 – 30 • Krebs Cycle • Electron Transport

  28. Question 3 - 40 • At the end of Electron Transport oxygen, the electrons, and the hydrogen ions combine to produce what?

  29. Answer 3 – 40 • Water

  30. Question 3 - 50 • What is the name of the enzyme (complex protein) through which the hydrogen ions flow by diffusion to generate ATP?

  31. Answer 3 – 50 • ATP Synthase

  32. Question 4 - 10 • Name the two types of Fermentation

  33. Answer 4 – 10 • Lactic Acid • Alcoholic

  34. Question 4 - 20 • Fermentation recycles what crucial molecule that is needed for Glycolysis to occur?

  35. Answer 4 – 20 • NAD+

  36. Question 4 - 30 • How many ATP does fermentation produce?

  37. Answer 4 – 30 • Zero, (fermentation recycles the NAD+ molecule to allow glycolysis to continue)

  38. Question 4 - 40 • What type of fermentation is used to produce these two commercial products: • Cheese • Bread

  39. Answer 4 – 40 • Cheese – Lactic Acid Fermentation • Bread – Alcoholic Fermentation

  40. Question 4 - 50 • Which process must happen first, fermentation or glycolysis? Explain

  41. Answer 4 – 50 • Glycolysis • NADH is required for Fermentation and it is produced in Glycolysis

  42. Question 5 - 10 • In the absence of oxygen, instead of aerobic respiration following glycolysis, glycolysis is followed by _______________

  43. Answer 5 – 10 • Fermentation

  44. Question 5 - 20 • When a phosphate group is removed from an ATP molecule, energy is ______________

  45. Answer 5 – 20 • Released

  46. Question 5 - 30 • Organisms extract energy stored in glucose through the process of cellular __________

  47. Answer 5 – 30 • Respiration

  48. Question 5 - 40 • During fermentation, either ethyl alcohol and carbon dioxide or ____________ is formed.

  49. Answer 5 – 40 • Lactic Acid
