When does fermentation take place in your muscle cells?
Lactic acid fermentation takes place in human muscle cells when strenuous exercise causes temporary oxygen shortages.
The two types of fermentation are alcoholic fermentation, and lactic-acid fermentation. Alcoholic fermentation, occurs in yeast and other single celled organisms. Lactic-acid fermentation occurs in muscle cells. Your muscles use it to create energy when there is not enough oxygen to use for normal respiration.
Fermentation is metabolic process associated with microbes under anaerobic conditions, but it can occur in humans (and others) too. When energy is being expended at a high rate at the time of glycolysis, under conditions where cells does not get enough oxygen, anaerobic respiration happens without the usual electron transport chain and lactic acid is formed. Technically, this is fermentation. When energy is being expended at a high rate at the time of glycolysis, under…
Fermentation takes place when there is absence of oxygen. Without oxygen, the ETC (electron transport chain) is unuable. Cells resort to another option. It is used by the cell not to generate energy directly, but to recycle NADH into NAD+ so that glycolysis can continue, as long as glucose is present. For example, yeast perform fermentation to obtain energy by converting sugar into alcohol. Bacteria perform fermentation, converting carbohydrates into lactic acid.
When your muscle cells are asked to perform work at an easy relaxed pace they take in glucose, fructose or sucrose plus oxygen from the blood, and using the "Aerobic Respiration" method, they generate cellular motion energy without releasing lactic acid. However, when your muscle cells are asked to perform strenuous work at an over-extended pace, (like your running away from a bear who wants to eat you). Then the oxygen becomes in short supply…
What are disadvantages of fermentation when compared to the processes aerobic and anaerobic respiration?
The process of fermentation is the second stage of cellular respiration when oxygen is not present. The first stage, glycolysis, is always able to take place because it is an anaerobic process. Following glycolysis is either fermentation or the Krebs Cycle depending on whether it is anaerobic or aerobic respectively. When anaerobic, without oxygen, fermentation takes place and produces bodily toxins such as ethyl alcohol and lactic acid. These are the disadvantages of fermentation.
