Presentation Transcript

  1. 9.3 Fermentation

  2. Fermentation • = process that releases energy from food molecules in the absence of oxygen • Occurs in cytoplasm • 2 types – • Alcoholic Fermentation • Lactic Acid Fermentation

  3. After glycolysis, pyruvic acid enters fermentation process • Some organisms  alcoholic fermentation • Pyruvate + NADH  Alcohol +CO2 + NAD+ • Ex. Yeast, some bacteria

  4. Most organisms  lactic acid fermentation • Pyruvate + NADH  lactic acid + NAD+ • Ex. Humans, some bacteria

  5. Exercise and Energy • Quick energy for short race  ATP in muscles and ATP from lactic acid fermentation • Energy for longer race  ATP from cellular respiration (oxidative)
