3. Cellular Respiration:
Chemical bond energy in food molecules is converted to a form usable by organisms
Energy is stored in the bonds of ATP (adenosine triphosphate)

4. Aim: How do living things accomplish anaerobic respiration?

5. 1) What do all living things do to acquire energy?
To get

6. 2) What is Anaerobic Respiration?
ENERGY
Organisms make ATP (energy) without oxygen.
3) This process is also called fermentation.
There are two types of anaerobic respiration:

7. Alcoholic Fermentation
What is the name of the first step that breaks down glucose?
Glycolysis
What is the chemical reaction?
Glucose  Alcohol+ 2CO2 + 2ATP
6) What is the net gain in ATP for this process?
2 ATP

8. Let’s make some wine!

9. Besides alcohol what else is a waste product of alcoholic fermentation?
Yeast is a unicellular
organism capable of
carrying out alcoholic
fermentation
CO2

10. Bakers Yeast The CO2 that is released during fermentation creates
bubbles and pockets that
make bread rise.

11. 7) Can we do anaerobic cell respiration?
Yes, when our muscles run out of oxygen they do lactic acid fermentation

12. Lactic Acid Fermentation
What is the name of the first step that breaks down glucose?
Glycolysis
8) What is the chemical reaction?
Glucose  2 Lactic Acid + 2 ATP
What is the net gain in ATP for this process?
2 ATP

13. Glucose has 90 x the energy of ATP
1 Glucose = 2 ATP
The rest is lost as heat & remains in alcohol or lactic acid

14. Types of Anaerobic cell respiration
Lactic acid fermentation
Glucose
2 ATP + Lactic acid
Alcohol fermentation
Glucose
2 ATP + 2CO2 + Alcohol

15. Why do bread and Swiss cheese have so many holes?

16. Alcohol fermentation vs Lactic A. Fermentation
What is the organic compound used by both?
Glucose
What is their main product?
2 ATP
How are they different?
Alcohol fermentation produces alcohol & carbon dioxide and lactic acid fermentation produces lactic acid
What organisms utilize alcohol fermentation?
Yeast and Bacteria
What organisms utilize lactic acid fermentation?
Bacteria & Animal muscle cells when they run out of oxygen

17. Where does the energy come from to change ADP to ATP?
From food (glucose) during cellular respiration
What is the energy used for when ATP is changed to ADP?
To perform life functions

18. What process is shown in the setup?
Cellular respiration?
What gas is being produced by the yeast?
Carbon dioxide
