  • Lactic Acid Fermentation
    • Reactants: Pyruvate and NADH
    • Products: NAD+ and lactate (lactic acid)
    • Occurs in Muscle cells and micro-organisms
    • Alcohol Fermentation
      • Reactants: Pyruvate
      • Products: Ethanol and CO2 (waste)
      • Occurs in Yeasts and some bacteria
Aerobic Respiration Anaerobic Respiration
Similarities
  • Both processes begin with the breakdown of sugar (glucose)
  • Both processes involve pyruvate
  • Both processes are involved in cellular respiration
Type of cells that perform the process
  • Cancer cells
  • Metabolic cells
  • Muscle cells
  • Yeast cells
Location within the cell
  • Mitochondria
  • Where oxygen is lacking (mitochondria for lactic acid and alcohol fermentation)
Oxygen requirements Oxygen is required for the process to occur Oxygen is not used in this type of respiration
Reactants and Products Reactants: Pyruvate NAD, CoA

Products: Acetyl CoA, NADH, CO2 (waste)

Reactants: Pyruvate and NADH

Products: NAD+ or ethanol

Energy Output 36 ATP molecules are produced through this process 2 ATP molecules are released through this process
