1. Fermintation 4.6

2. Glycolysis

3. KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen.

4. Fermentation is used in food production.
yogurt
cheese
bread

5. Fermentation allows glycolysis to continue.
Fermentation allows glycolysis to continue making ATP when oxygen is unavailable.
Fermentation is an anaerobic process.
occurs when oxygen is not available for cellular respiration
does not produce ATP

6. Fermentation allows glycolysis to continue making ATP when oxygen is unavailable.
NAD+ is recycled to glycolysis
Lactic acid fermentation occurs in muscle cells.
glycolysis splits glucose into two pyruvate molecules
pyruvate and NADH enter fermentation
energy from NADH converts pyruvate into lactic acid
NADH is changed back into NAD+

7. Fermentation and its products are important in several ways.
Alcoholic fermentation is similar to lactic acid fermentation.
glycolysis splits glucose and the products enter fermentation
energy from NADH is used to split pyruvate into an alcohol and carbon dioxide
NADH is changed back into NAD+
NAD+ is recycled to glycolysis

Energy Yield net gain of 2 ATP at the expense of 2 ATP
6-C glucose  TWO 3-C pyruvates
Free e- and H+ combine with organic ion carriers called NAD+  NADH + H+

20. Breakdown of Pyruvic Acid
Where mitochondria
Pyruvate (3-C)  Acetic acid (2-C)
3rd C forms CO2
Acetic acid combines with Coenzyme A to form ACETYL-CoA
