Lactic Acid is produced when a cell undergoes anaerobic respiration. In layman's terms, this is when a living cell is not receiving enough oxygen to produce the energy required to follow through it's functions. This does not necessarily mean you are not breathing correctly, but that lets say, you are running and require GREAT amounts of oxygen while your intake can supply only a limited amount. So, your muscles will switch to anaerobic respiration to produce the output needed with its limited amount of resources. The downside is, it produces Lactic Acid as well (but this is actually for our benefit because it helps produce the sensation of tiredness and muscle "ache" so that we calm down before we truly run out of oxygen to the point we pass out).
In yeast, anaerobic respiration causes the production of alcohol instead of lactic acid. This is why fermentation must be air tight so that oxygen cannot interrupt this process.

What conditions is lactic acid fermentation?
Simple answer:Under the condition of strenuous exercise with inadequate oxygen supply. ;DComplicated answer: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.Read more about that amazing process here:http://en.wikipedia.org/wiki/Cellular_respiration#Aerobic_respirationHOWEVER 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.Read more about that here.http://en.wikipedia.org/wiki/Anaerobic_exerciseThe muscle prefers to make energy using "aerobic methods", but in extreme situations, your muscle cells have a "turbo" option: "Anaerobic_respiration".This Scientific American Article answers your question:http://www.scientificamerican.com/article.cfm?id=why-does-lactic-acid-builAnd read this:http://en.wikipedia.org/wiki/Lactic_acid_fermentationAnswer #2: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.
What is the relationship between overexertion of muscles and the formation of lactic acid?
When muscles are overtaxed, the cardiovascular system can't supply enough oxygen to keep up with the needs of the tissue, and the muscle cells start fermentation to maintain a degree of energy production. The end product of the fermentation process (in this case) is lactic acid. (Pyruvate molecules are made from glucose - cf. glycolysis - but in the meantime, NAD+ coenzymes are reduced to NADH as a byproduct. In order for the process to continue, the NADH needs to revert to NAD+ and lose the hydrogen. The hydrogen is added onto pyruvate to form lactic acid).
Why acidity increase after the oxygen in milk has been used up?
Once the oxygen in milk has been used up, lactic acid bacteria start to metabolize lactose and produce lactic acid as a byproduct. This buildup of lactic acid leads to a decrease in pH and an increase in acidity in the milk.
Does your liver produce red blood cells in case of adults?
In case of the fetus, liver produces red blood cells. Red blood cells are produced by flat bones in case of adults. Given a challenge to produce the extra red blood cells, the liver may start producing red blood cells in adults also, as a last resort.
Does the Krebs cycle start with pyruvic acid and yield lactic acid or alcohol?
The Krebs cycle starts with acetyl-CoA, not pyruvic acid. It produces ATP, NADH, FADH2, and carbon dioxide but does not yield lactic acid or alcohol. Lactic acid fermentation and alcohol fermentation occur in the absence of oxygen.
Why do you get a burring sensation in your muscles during exercise?
that burning sensation is the lactic acid building up in your muscles when your muscles produce lactic acid the start to burn thats why you get the sensation
When a person is no longer able to deliver enough oxygen to muscle cells during heavy exercise the cells begin to carry out anaerobic respiration which is the same type carried out by many bacteria?
During anaerobic respiration, muscle cells start producing energy without oxygen by breaking down glucose into lactic acid. This process helps generate ATP to keep muscle contractions going, but it also leads to the accumulation of lactic acid, causing muscle fatigue and soreness. This type of respiration is common in situations where oxygen supply is limited, such as during intense exercise.
When are reproductive cells produced?
Reproductive cells start to produce when you hit puberty.

Does football produce lactic acid?
beacuse when a footballer start a match he uses glucose and when thats glucose runs out and ATP runs out you have no more energy and latic acid starts to build up in your legs and you get cramp
How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?
5 minutes
How does lactic acid fermentation occur?
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.
Can bad circulation cause sore muscles?
If you are talking about bad circulation of oxygen, then yes, because the cellular respiration needed to make the energy necessary for moving muscles requires oxygen. And without that oxygen the cells in your muscles have to switch gears and start making energy through Lactic acid fermentation, which as the name points out creates an acid within your muscle cells, therefore causing a soreness. If we're talking about poor circulation of blood then the muscle cells won't be able to acquire enough oxygen to have respiration occur, causing the same switch to fermentation.

What results when muscles use all available oxygen but continue to work that point as in a marathon race?
The muscles run out of readily available energy (ATP) within a few minutes and start turning sugar directly into energy (not as efficient but quicker) and produce lactate/lactic acid instead of carbon dioxide. this supplements the aerobic metabolism so you still need to breath to get oxygen to the cells turning sugar into energy via oxidative phosphorylation (aerobic process, efficient but not fast enough) and brain cells don't have the anaerobic function so still need oxygen.the lactic acid doesn't cause muscle soreness but is associated with it due to pH changes as shitloads of ATP is made (causes acidosis)lookup Anaerobic metabolism on wikipedia
How can your muscles produce enough energy to function properly?
Well, your body always has some kind of energy. If you eat, then it can use the food for energy for quite a while. If that runs out because you haven't eaten for a long time, then your body will start using fat for energy. If that runs out, then it will start using muscle (which is very bad, since your heart is a muscle). If you are very low on immediately available energy, your body will react by making you feel tired, so that it has time to convert more energy while your body sleeps.
