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.

Alcohol fermentation and lactic acid fermentation are similar because glucose is oxidized to two molecules of pyruvic acid. The difference between them is that alcohol fermentation yield two molecules of ATP also.
There are two main types of fermentation. One kind, things like yeast do, releases Co2 (Carbon Dioxide) and the other kind, our muscle cells do, releases lactic acid. Fermentation is anaerobic respiration and lactic acid is a product.
Both make ATP.
Both alcohol and lactate fermentation enable cells to produce ATP without using oxygen; they are the anaerobic (lacking in oxygen) alternative to cellular respiration. This is because they are extensions of glycolysis that can generate ATP solely by substrate-level phosphorylation, specifically by regenerating NAD+ by transferring electrons from NADH to pyruvate or pyruvate derivatives. NAD+ can then be reused in glycolysis to oxidize sugar. Remember that glycolysis uses two net molecules of ATP by substrate-level phosphorylation.Lactate fermentation, also known as lactic acid fermentation, occurs when NADH reduces pyruvate directly to form lactate as an end product, hence the name "lactate fermentation." More specifically, if one glucose molecule goes through glycolysis, 2 net ATP and 2 pyruvate molecules are produced and 2 NAD+ molecules are consumed. 2 NADH molecules and 2 H+ come and reduce the 2 pyruvate molecules, forming 2 lactate molecules and 2 NAD+. The 2 NAD+ molecules are then reused in glycolysis, enabling the cell to produce ATP even in the absence of oxygen. Lactate fermentation is used by some fungi and bacteria as well as in the dairy industry to produce yogurt in cheese. Another fun fact about lactate fermentation is that human muscle cells use lactate fermentation to make ATP when oxygen is scarce, such as during strenuous exercise. The resulting accumulation of lactate is partly what causes the muscle fatigue and pain that can result from exercise. But don't worry, the blood carries away the lactate to the liver where the lactate is converted back to pyruvate.Alcohol fermentation occurs when pyruvate is first converted to acetaldehyde, a 2-carbon compound, through the release of carbon dioxide from the pyruvate. Then, NADH reduces the acetaldehyde to ethanol. A more detailed look shows us that just like lactate fermentation, glycolysis produces 2 ATP and 2 pyruvate from one glucose molecule. However, unlike lactate fermentation, each pyruvate molecule releases a carbon dioxide, resulting in 2 carbon dioxide molecules and 2 acetaldehyde molecules (acetaldehyde = pyruvate - carbon dioxide). Then, similar to lactate fermentation 2 NADH and 2 H+ reduce the 2 acetaldehyde molecules, forming 2 ethanol molecules and 2 NAD+ and regenerating the supply of NAD+ needed to continue glycolysis. Alcohol fermentation is often used in bacteria in anaerobic conditions as well as in yeast. Interestingly, the carbon dioxide that is released in alcohol fermentation generated by a baker's yeast is what allows the bread to rise!

Both start with glycolysis... but once you reach pyruvic acid, they're very different. Respiration final product is an inorganic compound (oxygen) whereas fermentation final product is an organic compound (such as lactic acid or ethanol)

respiration and fermentation both extract energy from food
Alcohol fermentation and lactic acid fermentation are similar because glucose is oxidized to two molecules of pyruvic acid. The difference between them is that alcohol fermentation yield two molecules of ATP also.
Both fermentation and cellular respiration release energy from glucose and other food molecules, making them similar in their processes.

Methanol and ethanol are both alcohols, but have different boiling points. Ethanol is 78.37 °C, 352 K, 173 °F, while methanol is 64.7 °C, 338 K, 148 °F.
A) They are [CH3-CHOH] identical; and B) the distillation process is what transforms ethanol into eventually a pure form.
