- fermentation allows glycolysis to continue
- under normal conditions amount of oxygen is enough to allow cellular respiration to continue
- under exercise conditions oxygen is used up too fast
- causes an oxygen debt
- 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
- if you have no ATP, you die
- Lactic acid fermentation
- glycolysis splits glucose into two pyruvate molecule
- pyruvate and NADH enter fermentation
- Energy from NADH converts pyruvate into lactic acid
- NADH changed back into NAD+
- alcoholic fermentation is similar to lactic acid
- done by yeast and bacteria
- make alcohol instead of lactic acid
- fermentation used in yogurt, bread, alcoholic beverages, and cheese
