    Alcohol Fermentation
    • Alcohol fermentation produces ethanol. 
    • The chemical reaction of alcohol fermentation is as follows:
    • Pyruvic acid → CO2+ acetaldehyde + NADH→ ethanol + NAD+
    • The first reaction is catalyzed by pyruvate decarboxylase.
    •  A carboxyl group is removed from pyruvic acid, releasing carbon dioxide as a gas.
    • Acetaldehyde is made in this process.
    • The second reaction is catalyzed by alcohol dehydrogenase to oxidize NADH to NAD+ and reduce acetaldehyde to ethanol.
