1. In the presence of Oxygen, Cells convert energy stored in Glucose into ATP 1

2. Flow of Energy 2

3. 3 All living things must be able to convert glucose into ATP.

4. Adenosine Triphosphate 4

5. 5

6. Energy is released from Glucose through “burning” with oxygen. 6

7. Energy (in the form of glucose) is supplied by the foods you eat. 7

8. 8 Oxygen is supplied by the air you breathe, and Carbon dioxide is released into the atmosphere. O2O2

9. Plants make their own glucose through Photosynthesis

10. 10 Inside your cells, mitochondria use oxygen to release energy from glucose.

11. 11 Specific chemical reactions occur in each compartment of the mitochondrion.

12. 12 The most efficient release of energy occurs in three main stages of Cellular Respiration. Glucose Pyruvic acid O2O2 O2O2 H2OH2O H2OH2O CO 2

13. 13 Glycolysis splits glucose into 2 pyruvic acid molecules http://www.science.smith.edu/departments/Biology/Bio231/glycolysis.html

14. NAD + NADH An electron carrier Empty: no electronsCarrying electrons 14

15. 15 The Krebs Cycle releases energy from Pyruvic acid and produces CO 2 http://www.science.smith.edu/departments/Biology/Bio231/krebs.html

16. 16 Electron carriers (NADH & FADH 2 ) generate even more ATP in the Electron Transport Chain. http://www.science.smith.edu/departments/Biology/Bio231/etc.html

17. Oxidative Phosphorylation Detail (ETC) 17 http://www.youtube.com/watch?v=kN5Mtq AB_Yc

18. ATP Synthase Detail 18 http://www.youtube.com/watch?v=_97mnA _kKds&feature=related Watch the youtube video to learn how ATP Synthase works.

19. ATP Tally 19 Part of CR# NADH Produced # FADH2 produced # ATP produced Glycolysis Krebs Cycle ETC

20. Check for Understanding: 1.Explain why plants must do both, photosynthesis and cellular respiration? 2.Where in the cell does glycolysis, the Krebs cycle and the electron transport take place? 3.What is the final electron acceptor in Oxidative Phosphorylation (ETC)? 4.Which parts of the mitochondria are analogous to the parts of the chloroplast? Explain how they are alike.

21. Textbook Artist: You have been assigned to illustrate the biochemical pathways involved in cellular respiration. You should include the processes of glycolysis, the Krebs cycle and the Electron Transport Chain You should indicate the reactants and products of each phase You should include the total energy products for each phase Finally, indicate where in the cell each phase occurs.

22. Create an amusement park ride using one of the Cell Respiration processes as your inspiration. 1.Create an analogy for your starting material (glucose, or pyruvic acid) 2.Show how it will change throughout the ride 3.Show how energy molecules are produced (what will be the ATP released? Or NADH?) 4.Describe your ride, and how it relates to the CR process. 22

23. Create an amusement park using Cell Respiration as your inspiration. Use analogies for the starting materials, process and products of each process (like glucose might be 6 people on a ride together) 23
