involvement of oxygen
Lactic acid fermentation is less efficient than aerobic respiration because it produces only 2 ATP molecules per glucose molecule, whereas aerobic respiration can generate up to 36-38 ATP molecules. This inefficiency arises because lactic acid fermentation does not fully oxidize glucose; instead, it converts it into lactic acid, releasing less energy. Additionally, aerobic respiration utilizes oxygen to fully break down glucose into carbon dioxide and water, maximizing energy extraction.
In both the cases you get biological oxidation to get the pyruvate. In case of the yeast, you have got oxygen available. So you get one carbon bi oxide molecule out and the C 2 H 5 OH out. That is ethyl alcohol molecule out. In case of the Lactic acid, you have less of the oxygen available. So here you get C 3 H 6 O 3. This occurs in the muscle cells in rigorous exercise, in the absence of oxygen. Like when you run fast for 100 meter race.
Less likely means that it has more of a chance not to happen.
Fermentation
Muscles can rely on lactic acid fermentation to generate ATP for a limited duration, typically around 1 to 3 minutes during intense exercise. This anaerobic process produces ATP quickly but is less efficient than aerobic respiration and leads to the accumulation of lactic acid, which can contribute to muscle fatigue. Once the energy demands exceed this timeframe or lactic acid levels become too high, the muscles will require a shift to aerobic metabolism to continue ATP production.
Muscles can rely on lactic acid fermentation to produce ATP for a limited duration, typically around 1 to 3 minutes during intense exercise. This anaerobic process allows for quick energy production but is less efficient than aerobic respiration. As lactic acid accumulates, it can lead to fatigue and a decrease in muscle performance. Eventually, the body must switch to aerobic metabolism to sustain longer-duration activities.
it can happen at any time it less likely to happen at a young age due to high metabolism that's the least likely it is more likely to happen in the teen era+
The breakdown of glucose into ATP in the absence of oxygen is called anaerobic respiration. This process, also known as fermentation, occurs in the cytoplasm and is less efficient at generating ATP compared to aerobic respiration. The end products of anaerobic respiration depend on the specific pathway utilized by the organism, with lactic acid fermentation and alcohol fermentation being common examples.
Fermentation is an anaerobic process that produces ATP without the use of oxygen, while aerobic respiration is an aerobic process that generates ATP using oxygen. Fermentation produces lactic acid or alcohol as byproducts, while aerobic respiration produces carbon dioxide and water. Fermentation is less efficient in terms of ATP production compared to aerobic respiration.
A likely event, mathematically, is more then 50% likely to happen. An unlikely event is less then 50% likely to happen.
When muscle cells undergo a short-term fermentation process, primarily during intense exercise when oxygen supply is limited, they convert glucose into lactic acid through anaerobic glycolysis. This process allows for the rapid production of ATP, but it also leads to the accumulation of lactic acid, which can cause muscle fatigue and discomfort. Ultimately, this fermentation enables muscles to generate energy quickly, albeit less efficiently than aerobic respiration.
