1. KEY CONCEPT Anaerobic Respiration produces a small amount of ATP without oxygen.

2. Fermentation is an anaerobic process.
Fermentation occurs when oxygen is not available
Aerobic
Anaerobic cellular respiration

3. There are two types of Fermentation:
Lactic acid fermentation
occurs in muscle cells
#1: Glycolysis splits glucose into two molecules
#2: These molecules are converted into lactic acid

4. Alcoholic fermentation
Occurs in yeast organisms
The yeast feed on sugars and do only anaerobic respiration. Glycolysis breaks down the sugar which is converted into ethyl alcohol and carbon dioxide.

5. Aerobic vs. Anaerobic Respiration
Aerobic Respiration produces: _________ ATP
Anaerobic Respiration produces _______ ATP
Explain why humans need oxygen to live!
