1. Learning Goal 9.2 – 9.3.15  Students will understand that cell respiration is the controlled release of energy from organic compounds to produce ATP, which in turn is used to provide energy for metabolic processes.

2. Topic 2.8 Respiration

3. Breathe In... Breathe Out...  How is breathing related to the process of cellular respiration?  You will receive a petri dish  Observe the dish  Hold it close to your mouth and breathe on it  What do you observe?

4. Breathe In... Breathe Out...  How is breathing related to the process of cellular respiration?  You will receive a bottle of water with Bromthymol Blue indicator mixed with it.  DO NOT DRINK THE LIQUID!!!!!  Observe the color of the liquid  Take a straw, put it in the bottle and blow GENTLY  Blow for several minutes, observing color changes as they occur  Put the cap on the bottle and shake it.  Observe the color

5. What is Respiration?  Cellular respiration is the process by which the chemical energy stored in the bonds of organic molecules is released and partially captured in the form of ATP.

6. Overview of Aerobic Respiration  Reactants:  Oxygen  Organic compounds  Carbohydrates  Proteins  Lipids  Products:  ATP  Carbon Dioxide  Water

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

8. Aerobic Respiration Overview A catabolic process – molecule is broken down, energy is released.

9. 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

10. Energy Coupling

11. Substrate Level Phosphorylation

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

13. 32 – 34 ATP Oxygen is required!

14. Aerobic Respiration  Reactants:  Products:

15. Aerobic Respiration Overview:  Overall Equation:  C 6 H 12 O + 6 O 2 6CO 2 + 6 H 2 O  Reactants:  Sugar (glucose)  Oxygen  Products:  Carbon dioxide  Water
