Lactic Acid Fermentation
- Electrons are released during glycolysis are passed to provide to pyruvic acid to form two molecules of lactic acid.
- Carried out by many bacteria, most notably by lactic acid bacteria.
- Used for a quick burst of energy.
Alcohol Fermentation
- Begins with glycolysis to produce two molecules of pyruvic acid, two molecules of ATP and four electrons.
- Carried out by many bacterial and yeasts.
- Used for energy.

Do cells make ethanol as a waste of cellular respiration?
No, ethanol is a byproduct of fermentation...not aerobic or anaerobic respiration
Process used to make bread rise lactic acid fermentation or alcoholic fermentation?
alcohol fermentation -- the ethanol (alcohol) and carbon dioxide are produced by the yeast.
What does fermentation make in humans?
Lactic acid
What is the difference between ethanol fermentation and lactic acid fermentation?
lactic acid fermentation, is an enzyme converts pyruvic acid made during glycolysis into another three-carbon compound. Alcoholic fermentation, is to convert pyruvic acid into ethyl alcohol.
Which organisms perform Fermentation?
It depends on the exact definition of "fermentation"; people differ on this. Yeasts, plants under anaerobic conditions (e.g. waterlogged soils), and some bacteria can convert sugars into ethanol.
How do you make ethanol gas?
Ethanol gas is typically made through the fermentation and distillation of plant materials such as corn or sugar cane. The process involves breaking down the sugars in the plants using yeast, then distilling the fermented mixture to separate the alcohol (ethanol) from the water and other byproducts.
How do you make yeast from ethanol?
Yeast fermentation converts sugars into ethanol. To make yeast from ethanol, you would need to reintroduce the ethanol to a suitable yeast culture medium that contains essential nutrients for yeast growth. The yeast will consume the ethanol as a carbon source and begin to multiply, adapting to grow in the ethanol environment.
Describe the two types of fermentation In what organisms do they occur and what end products do they pr?
Lactic Acid and Alcholic fermentation. Alcoholic fermentation is used in bread dough and yeasts in order to make them rise. Lactic Acid fermentation is found in body muscles, especially when you excersise. It helps to keep you breathing by transmitting oxygen when your oxygen levels are low.
When do ethanolic fermentation take place?
Ethanol fermentation typically occurs in the absence of oxygen, such as during anaerobic respiration in yeast or other microorganisms. It is a metabolic process in which sugars are converted into ethanol and carbon dioxide.
What is the chemical process that results in alcohol production in winemaking and brewing beer?
The Ethyl alcohol (or ethanol) in wine and beer is the product from alcohol fermentation, where yeast convert the sugars into ethanol, commonly known as ethyl alcohol, and carbon dioxide (as a by-product).Cheers:)VinoEnology.com
How is yeast used in the fermentation process?
Yeast is used to convert natural sugars into alcohol (ethanol). As a by porduct it also produces CO2 which can be used to make drinks fizzy. For example champagne, where the final fermentation is undertaken within the bottle.
What occurs during fermentation?
Decrease in NADH, pyruvate is broken down into carbon dioxide and acetylaldehyde, NADH is oxidized to NAD+, and acetylaldehyde is reduced to make ethanol.
