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.

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; given that molecular oxygen is not consumed in the process, this is frequently referred to as "anaerobic glycolysis."
[glyco- + G. lysis, a loosening]

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.

Based on past studies showing that aerobic metabolism is predominant in events with different distances (16), and increases from the start until the end of cycling time trials (10), whereas anaerobic metabolism is important in the middle and final sections of time trials (10,17), we hypothesized that energy system contribution is correlated to overall performance, aerobic energy system contribution is correlated with speed at different sections of a time trial (start, middle, and end phase) and that glycolytic energy system contribution is strongly correlated with the end phase of a race.

Considering the results of studies on the functional importance of the PPARG Pro12 and 12Ala alleles, we assumed that the presence of the 12Ala allele in a genome, as an element of a system favouring glucose consumption mainly in anaerobic metabolism, ought to be especially beneficial for athletes subjected to short-term physical exertion of maximal intensity, during which muscle energy is produced mainly in anaerobic metabolism.
