1. Anaerobic ATP Formation

2. Three Types of Organisms
Aerobes – use oxygen and can’t survive without it (us – can be anaerobic if necessary)
Anaerobes – cannot survive in the presence of oxygen; strictly anaerobes (tetanus & botulism)
Facultative anaerobes – can use oxygen if present or they can be anaerobic or they are anaerobic but not harmed by oxygen (yogurt)

3. Anaerobic Pathways No oxygen AKA – Fermentation
Occurs in some bacteria and protists that live in marshes, swamps, mud, deep-sea sediments, digestive systems, and sewage treatment plants

4. The Beginning: Glycolysis
Glucose is split into two pyruvate molecules
Occurs in the cytoplasm
2 ATP molecules are needed to start the reaction
4 ATP and 2 NADH molecules are produced

5. Pyruvic Acid
Glucose

6. Lactate
Pyruvic Acid
Glucose

7. Lactate
Pyruvic Acid
Glucose
Ethyl Alcohol
Acetaldehyde

8. Anaerobic Electron Transport
Occurs in some bacteria
Electrons may move through transport systems in the plasma membrane and an inorganic compound in the environment is the final electron acceptor
