1. Anaerobic Respiration
Chapter 10.3

2. Important Molecules in anaerobic respiration
CO2: One of two products formed in alcoholic fermentation
Ethanol/ Ethyl Alcohol: One of two products formed in alcoholic fermentation
Lactic Acid/ Lactate: Product of lactic acid fermentation
Pyruvic Acid: Product of Glycolysis
(2 per glucose molecule)

3. Glycolysis
As in aerobic respiration Glycolysis is the first step. It will yield the only ATP created in anaerobic respiration

5. Alcoholic Fermentation
glucose → 2 ethanol + 2 CO2 +2 ATP
Occurs in many bacteria and Fungi

7. Lactic Acid Fermentation
glucose → 2 lactate + 2 ATP

9. Lactic Acid Burn
Runners burn when muscles are loaded with lactic acid which causes a burning sensation.
The body’s natural response is pain. In an effort to stop the exercise and take in oxygen.

10. Oxygen Debt
The amount of oxygen needed to convert that lactic acid build up back into pyruvic acid.
This is why an athlete breathes heavy after muscle cramps the body is maintaining homeostasis by converting lactic acid back to pyruvates for normal respiration to resume.

11. Efficiency of Respiration
Aerobic Respiration is roughly 20x more efficient than anaerobic respiration.
Aerobic respiration produces: ATP
Anaerobic respiration produces: 2 ATP
