Pyruvate is the end product of glycolysis, which is converted into acetyl coA that enters the Krebs cycle when there is sufficient oxygen available. When the oxygen is insufficient, is broken down anaerobically, creating lactate in animals (including humans) and ethanol in plants.
Fermentation. Yeast and other microorganisms can convert the end product of glycolysis, pyruvate, into ethanol in a two-step process. First, pyruvate is decarboxylated; that is, a carbon dioxide molecule from pyruvate is removed, creating acetaldehyde.The enzyme responsible for this reaction is called pyruvate decarboxylase.east and other microorganisms can convert the end product of glycolysis, pyruvate, into ethanol in a two-step process.
