1. Cell Respiration Aerobic vs Anaerobic

2. Let’s Review! Photo – CR cycle

3. What do these terms mean? Aerobic With oxygen Anaerobic Without oxygen

4. Aerobic Respiration Cell respiration in the presence of oxygen. It can produce 36 ATP for every molecule of glucose. (wow! That’s a lot!) C 6 H 12 O 6 + 6CO 2 6CO 2 + 6H 2 O + 36 ATP

5. Anaerobic Respiration Anaerobic respiration is cell respiration in the absence of oxygen. It will produce only 2 ATP molecules for every molecule of glucose. (oh my…that’s not too good…) Anaerobic respiration is also called fermentation.

6. Anaerobic Respiration Anaerobic respiration produces waste products. These waste products differ, depending on the species. In humans, the waste product is lactic acid. So, anaerobic respiration in humans is often called lactic acid fermentation.

7. Anaerobic Respiration in Animals (including people) AKA Lactic Acid Fermentation Lactic Acid Fermentation: Glucoselactic acid + 2 ATP

8. Anaerobic Respiration in Yeast AKA Alcoholic Fermentation The waste products of anaerobic respiration in yeast are carbon dioxide and alcohol. So, this is called alcoholic fermentation. Fermentation video 6 min Alcoholic Fermentation (only in yeast): Glucoseethanol + CO 2 +2 ATP

9. Alcoholic Fermentation Is very important to us from an economic standpoint: Bread Alcoholic beverages

10. Equations for Fermentation Lactic Acid Fermentation: Glucoselactic acid + 2 ATP Alcoholic Fermentation (only in yeast): Glucoseethanol + CO 2 +2 ATP
