1. Section 4.6
Fermentation

2. Fermentation
Allows glycolysis to continue making ATP when O₂ is unavailable.
An Anaerobic process.
Does NOT produce ATP

3. Lactic Acid Fermentation
Occurs in muscle cells of mammals.
What causes your muscles to burn during exercise.
Glycolysis splits glucose into 2 pyruvate molecules
NAD⁺ is recycled back in to glycolysis so it can continue.

4. Lactic Acid Fermentation
Pyruvate & NADH from glycolysis enter fermentation process.
- 2 NADH molecules provide energy to convert pyruvate into Lactic Acid
2 molecules of NAD⁺ recycled back into glycolysis.
- This allows glycolysis to continue

5. Lactic Acid Fermentation

6. Alcoholic Fermentation
Occurs in yeasts & some types of plants
Starts the same a Lactic Acid Fermentation
Glycolysis splits glucose
Produces NAD⁺
Different products formed = alcohol & CO₂
