Study Notes

Fermentation Overview

  • Fermentation is an anaerobic process, meaning it does not require oxygen.
  • The process of fermentation is essential for regenerating NAD+ to sustain glycolysis.

Types of Fermentation

  • Two main types of fermentation:
    • Alcohol fermentation
    • Lactic acid fermentation
  • Names of these fermentation types derive from their end products.

Alcoholic Fermentation

  • Example organisms:
    • Plants and fungi, notably involved in the production of beer and wine.
  • Reactants include:
    • ADP, NAD+, and NADH.
  • Products produced are:
    • 2 ATP, 2 CO2, and 2 ethanol (as waste).
  • An application of alcoholic fermentation is in bread making.

Lactic Acid Fermentation

  • Example organisms:
    • Animals are known to undergo this type of fermentation.
  • Reactants include:
    • ADP, NAD+, and NADH.
  • Products produced are:
    • ATP and lactic acid.
  • This fermentation type is primarily associated with animal metabolism rather than common kitchen use.
