Lactic acid is formed from pyruvic acid (often referred to as the ion, pyruvate, as the acid ion predominates at physiological pH values).
The reaction is catalyzed by an enzyme called lactate dehydrogenase. It involves the addition of two hydrogen atoms to convert pyruvate into lactate.
These H atoms are provided by the coenzyme NADH.
The pyruvate is the product of a series of anaerobic cell respiration reactions called glycolysis, which take place in the cytoplasm. Glycolysis converts a molecule of glucose into two molecules of pyruvate, with a net gain of two ATP molecules. In the course of glycolysis NAD+ is reduced to NADH. The conversion of pyruvate into lactate oxidizes the NADH, recycling it and so enabling glycolysis to continue.
In lactic acid fermentation, the pyruvic acid from glycolysis is reduced to lactic acid by NADH. NADH is nicotinamide adenine dinucleotide in a reduced form.

When During fermentation glucose is incompletely broken down to form?
During fermentation, glucose is incompletely broken down to form either ethanol (alcohol fermentation) or lactic acid (lactic acid fermentation) in order to regenerate NAD+ for glycolysis to continue in the absence of oxygen.
What sequence best summarizes lactic acid fermentation?
Glucose is broken down into pyruvate during glycolysis. Pyruvate is then converted to lactic acid in the absence of oxygen, regenerating NAD+ for glycolysis to continue.
What is lactic acid broken down into?
Lactic acid is broken down into lactate by the enzyme lactate dehydrogenase in a process called lactic acid fermentation. This conversion helps to regenerate NAD+ so that glycolysis can continue in the absence of oxygen.
What reactants do lactic acid fermentation and alcoholic fermentation have in common?
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.
Does lactic acid fermentation breaks down glucose to release energy in anaerobic respiration?
Yes, during lactic acid fermentation, glucose is broken down into lactic acid to generate energy in the absence of oxygen. This process occurs in muscle cells during strenuous exercise when oxygen supply is limited.
Is a process in which glucose is broken down into lactic acid and energy described as aerobic respiration?
No, lactic acid fermentation is anaerobic.
2 types of fermentation?
Two types of fermentation are alcohol fermentation and lactic-acid fermentation. Alcohol fermentation is the process in which 2 pyruvate molecules ,created by the means of glycosis, is further broken down into 2 ethanol molecules through alcohol fermentation. Lactic-acid fermentation is when the pyruvate molecules formed from glycosis is reduced to 2 lactate molecules.
When During fermentation glucose is incompletely broken down to form?
During fermentation, glucose is incompletely broken down to form either ethanol (alcohol fermentation) or lactic acid (lactic acid fermentation) in order to regenerate NAD+ for glycolysis to continue in the absence of oxygen.
What sequence best summarizes lactic acid fermentation?
Glucose is broken down into pyruvate during glycolysis. Pyruvate is then converted to lactic acid in the absence of oxygen, regenerating NAD+ for glycolysis to continue.
Which of the following is chemical byproduct of fermentation in humans?
Lactic acid is a chemical byproduct of fermentation in humans. It is produced when glucose is broken down in the absence of oxygen during anaerobic metabolism.
What is lactic acid broken down into?
Lactic acid is broken down into lactate by the enzyme lactate dehydrogenase in a process called lactic acid fermentation. This conversion helps to regenerate NAD+ so that glycolysis can continue in the absence of oxygen.
What is formed during the process of anaerobic lactic acid fermentation?
During anaerobic lactic acid fermentation, glucose is broken down into lactic acid and a small amount of energy (ATP) is produced in the absence of oxygen. This process occurs in muscles during high-intensity exercise when the demand for energy exceeds the oxygen supply.
What is lactic acid fermentaion?
Lactic acid fermentation is a metabolic process where glucose is converted into lactic acid in the absence of oxygen. This process is carried out by some bacteria and fungi, including lactobacilli, and is utilized in various food production processes such as yogurt and sauerkraut fermentation.
What is the name of the fermentation used by muscle cells?
The type of fermentation that sometimes occurs in human muscle cells is Lactic Acid fermentation.
What reactants do lactic acid fermentation and alcoholic fermentation have in common?

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.
Does lactic acid fermentation breaks down glucose to release energy in anaerobic respiration?
Yes, during lactic acid fermentation, glucose is broken down into lactic acid to generate energy in the absence of oxygen. This process occurs in muscle cells during strenuous exercise when oxygen supply is limited.
What happens to maltic acid in winemaking fermentaion does it increase or decrease form start to finish?
During winemaking fermentation, malic acid can be converted into lactic acid through a secondary fermentation process called malolactic fermentation. This can result in a decrease in malic acid levels towards the end of fermentation, depending on factors like temperature, yeast strains, and grape varieties.
