NOTES: 9.3 FERMENTATION

Vocabulary: -Fermentation -Aerobic -Anaerobic -Glycolysis -Lactic Acid Fermentation -Alcoholic Fermentation

What happens if your cells aren't getting enough oxygen?

Krebs Cycle & E.T.C. CANNOT proceed without oxygen

Instead, FERMENTATION occurs ? Pyruvic Acid builds up in animal muscle cells & is converted to LACTIC ACID... feel the burn!

? In other organisms, the pyruvic acid builds up, ferments, and becomes alcohol

 Fermentation: the release of energy from food molecules in the absence of oxygen (anaerobic)

Enables cells to carry out energy production in the absence of oxygen

result of glycolysis + fermentation yields 2 ATP molecules per 1 molecule of glucose (not nearly as much energy!!!!)
