2. Aim #39: How do living things accomplish anaerobic respiration?

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

4. 2) What is Anaerobic Respiration? ENERGY Organisms make ATP (energy) without oxygen.

5. 3) What is another word for anaerobic respiration? There are two types: 1) Alcohol Fermentation 2) Lactic Acid Fermentation Fermentation

6. Alcoholic Fermentation 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 Glucose + 2ATP + 2NAD +  2 Pyruvate + 2NADH + 4ATP 2 CO 2 + 2 Ethyl Alcohol Alcohol Fermentation

7. Let’s make some wine!

8. Besides alcohol what else is a waste product of alcoholic fermentation? CO 2 Yeast is a unicellular organism capable of carrying out alcoholic fermentation

9. Bakers Yeast The CO 2 that is released during fermentation creates bubbles and pockets that make bread rise.

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

11. 8) Lactic Acid Fermentation 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 Glucose + 2ATP + 2NAD +  2 Pyruvate + 2NADH + 4ATP 2 Lactic Acid Lactic Acid Fermentation

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 + 2CO 2 + 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 Acid Fermentation Review 1) What is the organic compound used by both? Glucose 2) What is their main product? 2 ATP 3) How are they different? Alcohol fermentation produces alcohol & carbon dioxide and lactic acid fermentation produces lactic acid 4) What organisms utilize alcohol fermentation? Yeast and Bacteria 5) What organisms utilize lactic acid fermentation? Bacteria & animal muscle ells when they run out of oxygen
