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 occur anaerobically. Lactic acid fermentation would occur in muscle and ethanol fermentation would occur by yeast. The end products are different of course as one produces lactic acid and the other ethanol. ...
In lactate fermentation, the product is lactate (lactic acid). In alcoholic fermentation, the product is ethanol (alcohol) and carbon dioxide.
The products of lactate fermentation are: cheese, yogurt, rye bread, and summer sausage.
The products of alcoholic fermentation are: fuel, beer, and wine.

Distinguish between the products of the two types of fermentation discussed in this section?
In alcoholic fermentation, the products are ethanol and carbon dioxide, produced by yeast during anaerobic conditions. In lactic acid fermentation, the product is lactic acid, produced by bacteria in muscles during strenuous exercise or in the fermentation of some food products like yogurt and sauerkraut.
What are the products of alcholic fermentation?
Alcohol fermentation is done by yeast and some kinds of bacteria. These microorganisms convert sugars in ethyl alcohol and carbon dioxide. Alcoholic fermentation begins after glucose enters the cell. The glucose is broken down into pyruvic acid. This pyruvic acid is then converted to CO2, ethanol, and energy for the cell. Humans have long taken advantage of this process in making bread, beer, and wine. In these three product the same microorganism is used: the common yeast or Saccharomyces Cerevisae.
In what industry is alcoholic fermentation important?
The economic importance of alcoholic fermentation is the production of bread and alcoholic beverages. Alcoholic fermentation is the driving force of the beer industry and the baked good industries.
What are the 2 types of fermentation and what do each produce?
The two types of fermentation are alcoholic fermentation, which produces ethanol and carbon dioxide, and lactic acid fermentation, which produces lactic acid.
What do both lactic fermentation and alcoholic fermentation produce?
Both lactic fermentation and alcoholic fermentation produce energy in the form of ATP for cells. Lactic fermentation results in the production of lactic acid, while alcoholic fermentation produces ethanol and carbon dioxide as byproducts.
What is a fermentation type?
Alcoholic and Lactate fermentation
What types of fermentation are there?
Alchoholic fermentation and Lactic Acid fermentation
Does the buildup of lactic acid in muscle cells result in alcoholic fermentation?
No, lactic acid buildup in muscle cells occurs during anaerobic respiration, not alcoholic fermentation. In alcoholic fermentation, glucose is converted into ethanol and carbon dioxide by yeast or some bacteria, not muscle cells.
The two main types of fermintation are called?
lactate fermentation (build up of lactic acid) and alcoholic fermentation (produces ethanol)
What does fermentation release with out using energy?
Alcohol fermentation releases carbon dioxide. The products of Lactic acid fermenation are 2 lactate.
How do humans use alcoholic fermentation?
Humans use alcoholic fermentation to produce beverages, foods, industrial liquids and many other important products.
What energy processes without oxygen?
Anaerobic respiration. Now there are two types: Alcoholic fermentation produces alcohol and occurs in plants and microorganisms like yeast. And lactate fermentation which produces lactate and occurs in animals - it is the lactate (or lactic acid) that causes muscle cramps when you have been running and your muscles havn't been getting enough oxygen. -Note: This is commonly referred to as just fermentation.
What is the name enzymes that catalyzes the formation of lactate during lactate fermentation?
lactate dehydrogenase
Both lactic acid fermentation and alcoholic fermentation produce?
Both lactic acid fermentation and alcoholic fermentation produce ATP as a form of energy for the cells. Additionally, both processes also produce waste products, such as lactic acid in lactic acid fermentation and ethanol in alcoholic fermentation.
What is different between the two types of fermentation?
The main difference between alcoholic fermentation and lactic acid fermentation is the end product produced. Alcoholic fermentation produces ethanol and carbon dioxide, while lactic acid fermentation produces lactic acid. Additionally, the microorganisms responsible for each type of fermentation differ, with yeast typically carrying out alcoholic fermentation and bacteria carrying out lactic acid fermentation.
