Anaerobic Respiration Alcoholic Fermentation

Anaerobic respiration and alcoholic fermentation are both processes that occur in the absence of oxygen and involve the breakdown of glucose to produce energy.

Alcoholic Fermentation:

  • Alcoholic fermentation is a specific type of anaerobic respiration that occurs in yeast and some other microorganisms.
  • In alcoholic fermentation, glucose is partially oxidized through glycolysis to produce energy in the form of ATP.

    Question : 2

    Fermentation is a kind of anaerobic respiratin done by bacteria and fungi . In it, food substrate lies outside the cell in a liquid medium and is oxidised to form organic acids of alcohol. This process is used in the manufacture of wine. Yeast is _________________
