Respuesta :
An organism relies on fermentation in situations where oxygen is no longer available.
What happens during fermentation?
In the absence of oxygen, enzymes of microbes break down sugars through the process of fermentation. Microorganisms like bacteria and fungus help in the process.
Lactic acid fermentation:
This anaerobic process involves the breakdown of starches or sugars to produce lactic acid as well as other waste products. In addition to preventing food from microbial deterioration, lactic acid bacteria also shield the body from microbial disease. Fermentation using lactic acid is frequently used to make foods like yogurt, pickles, and sauerkraut.
Alcohol fermentation:
During this form of fermentation, yeasts convert the pyruvate molecules in sugars into alcohol and carbon dioxide molecules, which are then used to make bread, wine, and beer.
