The chemical equation for alcoholic fermentation is: Pyruvate + NADH -> Ethanol + CO2 + NAD+

Glycolysis and Fermentation (Lactic Acid and Alcoholic).
The product of glycolysis is pyruvate. In alcoholic (ethanol) fermentation, pyruvate is converted into ethanol and carbon dioxide. The first step is decarboxylation, catalyzed by pyruvate decarboxylase: CH3COCOO- --> CH3CHO pyruvate --> acetaldehyde Then acetaldehyde is reduced to ethanol; this step is catalyzed by alcohol dehydrogenase and involves the oxidation of NADH+ + H+ to NADH: CH3CHO --> CH3CH2OH
Fermentation and glycolysis are two examples of anaerobic chemical reactions where energy is produced without the presence of oxygen.
Lactic Acid Fermentation and Alcoholic Fermentation.
Alcoholic fermentation is the type of fermentation that occurs in yeast.Anaerobic respiration, namely alcoholic fermentation. This process is very similar to glycolysis, except for the fact that alcoholic fermentation replaces one enzyme with two enzymes that change pyruvic acid into ethanol and carbon dioxide.
In the absence of oxygen, the products of glycolysis enter anaerobic pathways such as fermentation. This allows for the regeneration of NAD+ so that glycolysis can continue to produce ATP. Two common types of fermentation are lactic acid fermentation and alcoholic fermentation.
Yeast is one organism that uses alcoholic fermentation to allow glycolysis to continue producing ATP. In the absence of oxygen, yeast converts pyruvate to ethanol and carbon dioxide, regenerating NAD+ and allowing glycolysis to continue.
There are two types of fermentation: Alcoholic Fermentation and Lactic Acid Fermentation. Both types have the same reactants: Pyruvic acid and NADH, both of which are products of glycolysis. In alcoholic fermentation, the major products are alcohol and carbon dioxide. In lactic acid fermentation, the major product is lactic acid. For both types of fermentation, there is a side product: NAD+ which is recycled back to glycolysis so that small amounts of ATP can continue to be produced in the absence of oxygen.
Lactic acid fermentation and alcoholic fermentation are both anaerobic processes that convert glucose into energy without the use of oxygen. They involve glycolysis, where glucose is broken down into pyruvate, which is then transformed into either lactic acid (in lactic acid fermentation) or ethanol and carbon dioxide (in alcoholic fermentation). Both processes regenerate NAD+, allowing glycolysis to continue producing ATP. Additionally, both are utilized in various food and beverage production methods, such as yogurt for lactic acid fermentation and beer for alcoholic fermentation.
For alcoholic fermentation, the reactants required are glucose (sugar) and yeast. Yeast metabolizes glucose through glycolysis, resulting in the production of alcohol (ethanol) and carbon dioxide as byproducts.
