Section 4.6 Fermentation

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

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.

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

Lactic Acid Fermentation

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
