1. Learning Goal 9.4 – 9.8.15  Students will understand that aerobic respiration requires oxygen and gives a large yield of ATP from glucose that is immediately available as a source of energy for the cell. https://www.youtube.com/watch?v=EfGlznwfu9U

2. Topic 2.8 Respiration

3. What is Respiration?  Cellular respiration is the controlled release of energy from organic compounds to produce ATP. (Understanding 1)

4. What is Respiration?  ATP from cell respiration is immediately available as a source of energy in the cell. (Understanding 2)

5. Respiration  Respiration can occur in the presence or absence of oxygen.  Respiration that occurs in the presence of oxygen is called aerobic respiration.

6. Respiration  The release of energy that is stored in the bonds between organic molecules.  The energy is then used for life processes.  ATP transfers the energy from the reactions where it is released to the reactions where it is used.

7. Energy Coupling

8. ATP Hydrolysis

10. Aerobic Respiration Overview A catabolic process – molecule is broken down, energy is released. https://www.youtube.com/watch?v=-Gb2EzF_XqA

11. Glycolysis  Takes place in the cytosol  Requires an energy investment  Common to all life on Earth  Ancient process – virtually unchanged through life history  http://www.sumanasinc.com/webconten t/animations/content/cellularrespiration.h tml http://www.sumanasinc.com/webconten t/animations/content/cellularrespiration.h tml

12. Glycolysis

13. 2 ATP molecules needed to start the process 4 ATP molecules are produced, but there were two to begin with, so the net gain is 2 ATP molecules. 6 carbons 3 carbons

14. Glycolysis InputOutput Glucose (1)Pyruvate (2) ATP (2) ADP (4); P i (4)ATP (4) Substrate – level phosphorylation ( net of 2 when you subtract the investment of 2) 2NAD + 2NADH

15. Substrate Level Phosphorylation

16. Linking Reaction

18. InputOutput Pyruvate (1)CO 2 NAD + NADH Co-enzyme AAcetyl Co-A

19. Linking Reaction Also known as the Kreb cycle. Occurs twice for each glucose molecule. 2 more ATP

20. Krebs Cycle (Citric Acid Cycle)

21. InputOutput Acetyl Co-ACoenzyme A; CO 2 (2) NAD (3)NADH (3) + H + (3) FADFADH 2 ADP + PiATP

22. 32 – 34 ATP Oxygen is required!

23. Electron Transport Chain https://www.youtube.co m/watch?v=KGjCm566- MY

24. Electron Transport Chain InputOutput NADHNAD FADH 2 FAD ½ O 2 H2OH2O
