Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O 2) are available. [1] This occurs in health as in exercising and in disease as in sepsis and hemorrhagic shock. [1] providing energy for a period ranging from 10 seconds to 2 minutes.
The anaerobic glycolytic energy pathway is the source of human energy after the first 30 seconds of an exercise until 3 minutes into that exercise. The first 30 seconds of exercise are most heavily reliant on the phosphogenic pathway for energy production.
Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
Bioenergetic systems are metabolic processes that relate to the flow of energy in living organisms. Those processes convert energy into adenosine triphosphate (ATP), which is the form suitable for muscular activity. There are two main forms of synthesis of ATP: aerobic, which uses oxygen from the bloodstream, and anaerobic, which does not.

Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...
Nearly all organisms that break down glucose utilize glycolysis. [2] Glucose regulation and product use are the primary categories in which these pathways differ between organisms. [2] In some tissues and organisms, glycolysis is the sole method of energy production. [2] This pathway is common to both anaerobic and aerobic respiration. [1]
Anaerobic respiration is correspondingly less efficient than aerobic respiration. In the absence of oxygen, not all of the carbon-carbon bonds in glucose can be broken to release energy. A great deal of extractable energy is left in the waste products. Anaerobic respiration generally occurs in prokaryotes in environments that do not contain oxygen.
In practical terms, this means that anaerobic exercise is more intense, but shorter in duration than aerobic exercise. [2] Fox and Haskell formula. The biochemistry of anaerobic exercise involves a process called glycolysis, in which glucose is converted to adenosine triphosphate (ATP), the primary source of energy for cellular reactions. [3]
