• Muscles tend to expend ATP at a faster pace compared to the supply of oxygen to muscle cells. This leads to the accumulation of lactic acid, and hence the sore muscles.
• • Lactic acid Fermentation
  • Ethanol fermentation
  • Acetic acid fermentation

  Types of fermentation
• Lactic acid fermentation

  Starch to lactic acid
• ethanol fermentation

  starch to ethanol + CO2 (glycolysis)
• acetic acid fermentation

  starch to vinegar (glycolysis)
• The purpose of lime water is to check the fermentation reaction.
• Positive result seen should be the presence of carbon dioxide (white bubbling) precipitate in lime water, as this is one of the by product of fermentation.
