Description
Yeast converts fermentable sugars into ethanol and CO₂ under anaerobic conditions.
Technical
The process begins with glycolysis, producing pyruvate, which is decarboxylated to acetaldehyde by pyruvate decarboxylase. Acetaldehyde is then reduced to ethanol by alcohol dehydrogenase, releasing CO₂ as a by‑product. Temperature, pH, oxygen, and yeast strain selection critically influence yield and flavor.
Science
