glycolysis

 [gli-kol´ĭ-sis]
the anaerobic enzymatic conversion of glucose to lactate or pyruvate, resulting in energy stored in the form of ATP, as occurs in muscle. adj., adj glycolyt´ic.

gly·col·y·sis

(glī-kol'i-sis),
The energy-yielding conversion of d-glucose to lactic acid (instead of pyruvate oxidation products) in various tissues, notably muscle, when sufficient oxygen is not available (as in an emergency situation); because molecular oxygen is not consumed in the process, this is frequently referred to as "anaerobic glycolysis" Compare: Embden-Meyerhof-Parnas pathway.
Synonym(s): glucolysis
[glyco- + G. lysis, a loosening]

glycolysis

(glī-kŏl′ə-sĭs)
n.
A metabolic process that occurs in nearly all living cells in which glucose is converted in a series of steps to pyruvic acid and during which energy is released in the form of ATP.

gly′co·lyt′ic adj.

glycolysis

[glīkol′isis]
Etymology: Gk, glykys + lysis, loosening
a series of enzymatically catalyzed reactions by which glucose and other sugars are broken down to yield lactic acid (anaerobic glycolysis) or pyruvic acid (aerobic glycolysis). The breakdown releases energy in the form of adenosine triphosphate (ATP). Also called Embden-Meyerhof pathway. See also citric acid cycle, lactic acid.

glycolysis

The breakdown of glucose or other sugars under the influence of enzymes, with the formation of lactic acid or pyruvic acid and the release of energy in the form of adenosine triphosphate (ATP). The complex biochemical sequence by which glucose-6-phosphate is converted to pyruvate and ATP.

glycolysis

‘sugar-splitting’, the first stage of CELLULAR RESPIRATION, occurring with or without the presence of oxygen, in which glucose is converted to two molecules of pyruvic acid. See Fig. 177 . See also AEROBIC RESPIRATION.

Glycolysis

The pathway in which a cell breaks down glucose into energy.

glycolysis

a catabolic pathway that breaks down glucose 6-phosphate, derived from glucose or glycogen, and in the process generates energy which leads to production of ATP. In aerobic conditions, pyruvate is the end-product. In conditions when oxygen cannot be utilized anaerobic glycolysis involves the additional step of reducing pyruvate to lactate. See also aerobic exercise, anaerobic exercise.

glycolysis (glīkol´isis),

n 1. the oxidation of glucose or glycogen by cytoplasmic enzymes of the Embden-Meyerhof pathway to pyruvate and lactate.
2. a series of enzymatically catalyzed reactions occurring within cells, by which glucose and other sugars are broken down to yield lactic acid or pyruvic acid, releasing energy in the form of adenosine triphosphate.

glycolysis

the enzymatic conversion of glucose to lactate or pyruvate, resulting in chemical bond energy stored in the form of ATP, as occurs in all tissues.

In 1997, Biswas and others with the Indian Institute of Chemical Biology in Calcutta concluded that methylglyoxal (an aldehyde form of pyruvic acid) could hinder glycolysis and mitochondrial respiration due to its ability to inhibit glucose utilization and glucose 6-phosphate (G6P) and Llactate formation in the whole EAC cells [20].
Third, the lack of decrease in LA occurred due to absence of inhibition in glycolysis and glycogenolysis.
