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.

During lactic acid fermentation, pyruvate, a product of glycolysis, is converted into lactic acid by the enzyme lactate dehydrogenase. This process helps regenerate NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen. Lactic acid fermentation is commonly used in the production of dairy products like yogurt and cheese.

I 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.

Lactic 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.

lactic 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

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. 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.

To produce energy (ATP) for whatever is triggering the process (bacteria and other simple lifeforms). In humans, lactic acid is produced through anaerobic respiration rather than fermentation.

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.
