Study Notes
Fermentation Process
- Fermentation is a metabolic process that converts sugars into acids, gases, or alcohol in the absence of oxygen.
- Commonly known types of fermentation include alcoholic fermentation (producing ethanol) and lactic acid fermentation (producing lactic acid).
Products of Fermentation
- Sugar fermentation typically produces alcohol, carbon dioxide, and various organic acids.
- Ethanol and carbon dioxide are the main byproducts in alcoholic fermentation, while lactic acid is the primary product in lactic acid fermentation.
Characteristics of Fermentation
- Characteristics of fermentation include anaerobic conditions, energy production without oxygen, and involvement of microorganisms.
- A key feature that is NOT associated with fermentation is the requirement for oxygen, making it distinct from aerobic respiration.
Role of Sugar in Fermentation
- Sugar serves as a primary substrate for fermentation, providing energy for microorganisms.
- Different sugars, such as glucose, fructose, or sucrose can be fermented, varying the end products depending on the pathway.
Overall Outcome of Fermentation
- The overall outcome of fermentation is the conversion of glucose into energy, producing byproducts like alcohol or lactic acid.
- Fermentation allows for regeneration of NAD+, essential for glycolysis continuation and energy production in anaerobic conditions.
