  1. Photosynthesis vs. Cellular Respiration Cellular Energy & Biochemistry Chapter 5

  2. Photosynthesis (autotrophs) CO2 + H2O C6H12O6 + O2 Carbon dioxide Glucose & & water oxygen Respiration (heterotrophs)

  3. Energy Cycle Photosynthesis Respiration Autotrophs Herbivores Carnivores

  4. Releasing Energy from Foods

  5. What is the function of photosynthesis? • Energy storage Converts light energy to chemical energy in the form of glucose.

  6. What are the two stages of photosynthesis? Light Calvin Reactions Cycle requires light light independent

  7. What is the formula for glucose? • C6H12O6

  8. Where in the cell does photosynthesis take place? • Thylakoid membranes ofchloroplasts.

  9. Where in the chloroplast does the Calvin cycle take place? • Grana of chloroplast

  10. What is the equation for Photosynthesis? • 6CO2 + 6H2O → C6H12O6 + 6O2

  11. What are the reactants of Photosynthesis? • CO2 and H2O

  12. What are the products of Photosynthesis? • C6H12O6 and O2

  13. What is the function of Cellular Respiration? • Energy release Breaks down glucose to form ATP for cellular activities

  14. Cellular Respiration Glycolysis (yields ATP) AerobicAnaerobic (oxygen) (w/o oxygen) fermentation Yields 21- 36 Yields 2 ATP ATP

  15. Anaerobic Respiration Alcohol Lactic Acid Fermentation Fermentation Alcohol & CO2 Lactic acid + CO2 baking, sours milk, brewing muscle fatigue

  16. What is glycolysis and where does it take place? Glycolysis breaks down glucose into pyruvic acid in the cytoplasm

  17. How many molecules of ATP does glycolysis produce? • 2 molecules of ATP

  18. How many molecules of ATP does Cellular Respiration produce? Glycolysis 2 ATP Aerobic + 36 ATP Total 38 ATP

  19. Where in the cell does Cellular Respiration take place? • Mitochondria – 2 membrane (outer and inner folds cristae)

  20. Energy Release/Storage Cycle ATP= Adenosine Tri Phosphate (A-P-P-P) ADP = Adenosine Di Phospate (A-P-P) A-P-P - P energy energy storage release A-P-P + P

  21. What is the equation for Cellular Respiration? • C6H12O6 + 6O2 → 6CO2 + 6H2O (+ Energy in form of ATP)

  22. What are the reactants of Cellular Respiration? • C6H12O6 and O2

  23. What are the products of Cellular Respiration? • CO2 and H2O
