Yeast fermentation converts sugars into ethanol and CO₂ via glycolysis and alcoholic fermentation.
Origin: Ancient civilizations (Ancient to modern) — Worldwide
See full technique reference →During glycolysis, glucose is broken down to pyruvate, generating ATP and NADH. Pyruvate is decarboxylated to acetaldehyde, which is then reduced to ethanol by alcohol dehydrogenase, regenerating NAD⁺ for continued glycolysis. The overall yield is about 0.511 g ethanol per g glucose under optimal conditions.
Primary Reaction
