Lactic acid is produced in the body during intense exercise when oxygen levels are low. It helps to convert glucose into energy and can be used as a fuel source by muscles. Additionally, lactic acid can be converted back into glucose in the liver, providing a way to replenish energy stores.
In the absence of oxygen after glycolysis, muscle cells will produce lactic acid through the process of fermentation. This allows the cells to regenerate NAD+ needed for glycolysis to continue in the absence of oxygen.
The by-product of lactic acid fermentation is lactic acid. This process occurs in muscle cells when oxygen is in short supply, leading to the production of lactic acid as a way to generate energy. Lactic acid can build up in muscles and cause fatigue and muscle soreness.
The synthesis of lactic acid occurs in the cytoplasm of vertebrate animal cells through the process of anaerobic glycolysis. This metabolic pathway converts glucose into lactic acid when oxygen is limited.
The conversion of pyruvic acid to lactic acid occurs in the cytoplasm of the cell. This process, known as lactic acid fermentation, is a way for cells to regenerate NAD+ from NADH in the absence of oxygen.
The liver converts lactic acid to glucose, which it then can convert to glycogen for storage.
The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen is the oxygen debt. Threshold stimulus is the minimal amount of energy required to contract a muscle fiber.
The liver will extract lactic acid from the blood stream and convert it into glycogen, a reserve fuel type of energy.
Lactate (also known as lactic acid) and NAD+
Lactic acid fermentation converts pyruvate into lactic acid in the absence of oxygen. This process occurs in muscle cells during strenuous exercise when oxygen levels are low, leading to the buildup of lactic acid and temporary muscle fatigue.

Human muscle cells use lactic acid fermentation primarily during intense exercise when oxygen levels are low. This process allows for the rapid production of ATP, the energy currency of the cell, by converting glucose into lactic acid. While this enables sustained muscle contraction during short bursts of activity, the accumulation of lactic acid can lead to muscle fatigue. Ultimately, lactic acid can be converted back to glucose in the liver once oxygen levels are restored.
Lactic acid is produced in the body during intense exercise when oxygen levels are low. It helps to convert glucose into energy and can be used as a fuel source by muscles. Additionally, lactic acid can be converted back into glucose in the liver, providing a way to replenish energy stores.
Lactic acid comes from dairy products. So vegetarians can eat it but vegans will not. Lactic acid is also found in muscle cells.
The skeletal system itself does not directly remove lactic acid; instead, lactic acid is primarily processed by the liver and muscles. During intense exercise, lactic acid is produced as a byproduct of anaerobic metabolism. While the skeletal muscles can utilize lactic acid for energy, the liver converts it back into glucose through a process called gluconeogenesis. Thus, the skeletal system plays a role in the overall metabolism of lactic acid, but it does not remove it on its own.
Muscle cells in oxygen deprivation convert pyruvate to lactate through a process called anaerobic glycolysis. This allows for the generation of ATP in the absence of oxygen, but results in the build-up of lactate in the muscles, leading to muscle fatigue and soreness.
