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.
