Document Summary
Metabolic process (anaerobic cellular respiration) occurring in bacteria, yeasts, and oxygen-deprived muscle cells: uses sugar to produce energy. doesn"t use oxygen. we burn sugars as well. It is respiration because it is the burning of sugars. It is aneraboic because it: our body is capeable of fermentation. When our body is deprived of oxygen taste like chocolate. Milk: talking about fermentation done by bacteria and yeasts. It is used by humans to process food. When bacteria and yeasts ferment food they produce changes and in some cases those changes are desirable. Bacteria and yeasts breaks down sugars and produces other substances these. A kind of fermentation where the substances change the flavour, texture taste. main results are alcohol and carbon dioxide. The main result/product of reaction is lactic acid. One of the main purposes of this process is that it helps to preserve the food. Both alcohol and lactic acid help preserve food.
