In humans, lactic acid occurs in aneroobic condition. when you do not have enough oxygen but you still need energy. Normally, oxidative phosphorylation occurs when there is enough oxygen. Instead a lack of oxygen requires--in humans of course to have this occur: NADH reduces lactate dehydrogenase to generate lacate. why this occurs is so your body can continue functioning. e.g if you were working out this lactic acid builds up. Normally enough oxgen would breakdown glucose through oxidative phoshorlyation. This lactic acid that builds up is actually toxic-- your body ends up converting some of that lactic acid to carbon dioxide and water.

∙ 14y agoI can tell you lactic acid build-up occurs in the muscles and is released as a waste product into the blood after working the muscles. This is what causes soreness and muscle fatigue after working out strenuously. What I think you are talking about is the process of the body to turn sugars such as fructose into energy that can be used in cells and can be metabolized. Lactic acid fermentation occurs in cardiac muscles, the liver and any other oxygen starved muscles.

∙ 12y agoLactic acid fermentation occurs in the absence of oxygen (it's anaerobic). Basically, it's glycolysis (the breakdown of a sugar - most of the time glucose is used as an example) to produce 2 ATP and 2NADH (NAD+ and 2 electrons) and 2 pyruvate molecules in the end. The pyruvate is then converted into lactate (the complementary base of lactic acid), using 1 NADH per lactate molecule, thus making NADH NAD+ again so that it can continue glycolysis. While no NADH is produced, 2 ATP per cycle of glycolysis are. The synthesized waste lactic acid is likely excreted from the cell, into its surroundings.
It's the source of energy in many bacteria and these bacteria are in turn used to make food, such as yogurt, kimchi, and sauerkraut. It also occurs in other organisms too - when there's not enough oxygen for the mitochondrion's electron transport chain, the cell reverts to just glycolysis which leads to lactic acid fermentation. This happens quite commonly - the 'burn' you feel when you exercise is due to the build up of lactic acid in your muscles because they're not getting oxygen fast enough.
There is a process similar to this, you may have heard of it - alcohol fermentation.

∙ 13y agolactic acid fermentation occurs when muscles start breathing anaerobically i.e in the absence of oxygen and produce lactic acid.when we do a lot of exercise our muscles are not able to get enough oxygen that is needed and they start breaking glucose in the absence of oxygen which produces lactic acid and causes sprain

∙ 10y agoWhen 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. There is not enough oxygen supplied by the lungs to increase output under the "Aerobic Respiration" method.
So, the muscle cells, knowing that they will die if they don't produce more energy, have a Plan - B. They can create massive amounts of energy without oxygen with the drawback of creating lactic acid. But that's fine, they will clean up that mess later. They start using an "Anaerobic Respiration" method.
The muscle prefers to make energy using "aerobic methods", but in extreme situations, your muscle cells have a "turbo" option: "Anaerobic_respiration".
Answer:Your muscle cells will undergo lactic-acid fermentation (Creating cellular energy anaerobically) when there is not enough oxygen in the blood to create cellular energy in the preferred aerobic way.Wiki User

Lactic Acid fermentation :)
Lactic acid (or lactate, which is the anion of lactic acid) is the product of lactic acid fermentation.
lactic acid can also be produced in lactic acid fermentation when oxygen is absent. in this process, pyruvic acid is reduced to lactic acid and NADH is oxidized to NAD+.
During lactic acid fermentation of glucose,Pyr + NADH --> Lactic acid + NAD(+)During this process NADH donates it's 2 electrons associated with its proton of H, pyruvate acceptsthoseelectrons, and lactic acid is the final reduced product
ALCHOLIC FERMENTATION:- It occurs in bacteria,yeast etc. In this type of anaerobic resipiration pyruvic acid is further broken down into alcohol. Lactic fermentation:- It occurs in skeletal muscles of humans and other animals during extreme physical activities (when oxygen supply is not sufficent) and in bacteria present in milk. In lactic acid fermentation pyruvic acid is converted to lactic acid.This process is involved in the production of yogurt.
Making saurkraut is a lactic acid fermentation.
Lactic acid and fermentation occur during anaerobic metabolism.
The fermentation of milk occurs to form curd, of course lactic acid is released.
*muscle cells
Lactic acid fermentation is an anaerobic process. This means that lactic acid is produced in the absence of oxygen. This usually occur in bacteria cells but can also occur in muscle cells.

Yes? lactic acid fermentation produces only lactic acid alcoholic fermentation produces ethanol and co2
Both occur anaerobically, or with exercise, but lactic acid occurs in muscles (you know that burning sensation after muscle fatigue? It's from lactic acid buildup in muscles) and alcoholic fermentation occurs by yeast. So basically, the main thing that they have in common is just that they occur anaerobically.
