Study Notes
Fermentation Types
- Alcoholic fermentation converts glucose (C6H12O6) into ethanol, carbon dioxide (CO2), and produces 2 ATP.
- Lactic acid fermentation also begins with glucose (C6H12O6) but produces lactic acid and 2 ATP instead.
Glycolysis
- Glycolysis is the initial step in both fermentation processes, where glucose is broken down into pyruvate.
Indicators of Fermentation
- The presence of carbon dioxide (CO2) during fermentation is evidenced by the inflation of balloons.
Aerobic Respiration
- Aerobic respiration requires glucose (C6H12O6) and oxygen (O2), producing carbon dioxide (CO2), water (H2O), and ATP.
Oxygen's Role
- Fermentation occurs in the absence of oxygen (O2), indicating it is an anaerobic process.
Carbohydrates
- The term "carbohydrate" translates to "carbon hydrated with water," reflecting its molecular structure.
Key Organelles
- Mitochondria are the organelles primarily involved in aerobic respiration.
Products of Glycolysis
- Pyruvate is the main product of glycolysis, which can be further converted into ethanol and carbon dioxide during alcoholic fermentation.
Yeast and Fermentation
- Yeast primarily utilizes alcoholic fermentation to generate energy.
