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

2. What do all living things do to acquire energy?
To get

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

4. TWO TYPES OF ANEROBIC RESPIRATION
Alcohol Fermentation
Lactic Acid Fermentation
All Cellular Respiration begins with glycolysis.
Changing glucose into 2 pyruvic acid.
This makes 4 ATP but cost 2ATP to happen.
This happens in the cytoplasm of the cell.

5. How are these things made?
Lactic Acid Fermentation
Alcohol Fermentation
Bacteria
Yeast

6. Alcohol Fermentation = Glycolysis
Glucose  2 Pyruvic Acid  2 CO2 + 2 Ethyl Alcohol
2 ATP
What is the name of the process that converts glucose into pyruvic acid?
Glycolysis
What is the net gain in ATP for this process?
2 ATP

7. Let’s make some wine!

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

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

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

11. Lactic Acid Fermentation
Glucose  2 Pyruvic Acid  2 Lactic Acid
2 ATP
What is the name of the process that converts glucose into pyruvic acid?
Glycolysis
What is the net gain in ATP for this process?
2 ATP

12. Let’s work out & feel the burn

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
Alcohol fermentation
Glucose
2 ATP + 2CO2 + Alcohol
Lactic acid fermentation
Glucose
2 ATP + Lactic acid

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 and lactic acid fermentation produces lactic acid

17. Alcohol fermentation vs Lactic Acid Fermentation
What organisms utilize alcohol fermentation?
Yeast and Bacteria
What organisms utilize lactic acid fermentation?
Bacteria & Animal muscle cells when they run out of oxygen
