- From equations (1) and (2), we get the lactic acid formation equation: Glucose + ADP + NADH -> C 3 H 6 O 3 (Lactic Acid) + ATP + NAD+ This lactic acid fermentation pathway where glucose is first broken down to pyruvate by glycolysis, then the glucose to pyruvate producing 2 ATPs is called homolactic acid fermentation.
In lactic acid fermentation, NADH transfers its electrons directly to pyruvate, generating lactate as a byproduct. Lactate, which is just the deprotonated form of lactic acid, gives the process its name.

In yeast, there is incomplete oxidation of glucose that happens in an anaerobic environment. Here, pyruvic acid is converted into carbon dioxide and ethanol. Some bacteria produce lactic acid from pyruvic acid by means of lactic acid fermentation.

If oxygen is unavailable, lactic acid fermentation occurs, recycling pyruvate and NADH to produce more NAD+ for glycolysis. This process is common in organisms like lactobacillus, which is used in making yogurt, kimchi, and sauerkraut.

Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.
In muscles, lactic acid produced by fermentation must be removed by the blood circulation and brought to the liver for further metabolism. The chemical reaction of lactic acid fermentation is the following: Pyruvicacid + NADH ↔ lacticacid +NAD+ Pyruvic acid + NADH ↔ lactic acid + NAD +.
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells. In alcoholic fermentation, pyruvic acid changes to alcohol and carbon dioxide.
