UPSC CAPF – 2021
1. Aerobic respiration (in the presence of oxygen): Pyruvate is completely oxidized to carbon dioxide (CO₂) and water (H₂O).
2. Anaerobic respiration (fermentation, in the absence of oxygen): Pyruvate is converted into products like ethanol and carbon dioxide (in yeast and plants) or lactic acid (in muscle cells and some bacteria).
Ethanol, lactic acid, and water are all potential breakdown products of glucose during respiration. Methanol is not produced during the standard biological breakdown of glucose.
