2. CELLULAR ENERGIES

3. Where is energy created in a eukaryotic cell?

4. What about in prokaryotic cells?

5. 2007-2008 ATP What is energy in biology? Whoa! HOT stuff! Adenosine TriPhosphate

6. ATP: energy molecule

7. What is energy? Calorie = Energy A calorie is a heat unit of energy

9. ATP CYCLE

10. How do we define Cellular Respiration? Release energy from food to make ATP

11. Who does Respiration? All Living Organisms!

12. Aerobic Resp Anaerobic Resp. Req. OXYGEN Makes a LOT ATP NO OXYGEN Makes a LITTLE ATP

13. PROTIST Aerobic or Anaerobic? BACTERIA FUNGUS (YEAST) PLANTS ANIMALS

14. ANAEROBIC 1 st Step: Glycolysis – Splitting of Glucose EXERGONIC (energy releasing) Phosphorylation NAD

15. Where does glycolysis occur? CYTOPLASM

16. Flow Chart

17. FERMENTATION Respiration with NO oxygen

18. Chapter 23 Bacteria and Yeast in Food Production

19. What happens to the pyruvate? FERMENTATION: yeast & bacteria

20. Fermentation in Humans Build up of Lactic Acid in Muscles Lack of Oxygen

21. IN HUMANS

22. Choose your own adventure!

23. AEROBIC RESPIRATION Where does it occur in a cell?

24. Why the extra layers? Increase Surface Area MITOCHONDRIA

25. AEROBIC RESPIRATION STEP 1: Glycolysis Glucose Pyruvate If O2 is present! STEP 2: Kreb Cycle STEP 3: Electron Transport Chain (ETC)

26. From Food To ATP

28. Glucose CO 2 + H 2 O ATP released for cellular work many tiny steps

29. All organic molecules!

30. Who does photosynthesis?

31. Chemoautotrophs

32. CHLOROPLAST Increase Surface Area

33. CHLOROPHYLL green pigment converts solar energy into chemical energy (ATP)
