glycolysis /gly·col·y·sis/ (gli-kol´ĭ-sis) the anaerobic enzymatic conversion of glucose to the simpler compounds lactate or pyruvate, resulting in energy stored in the form of ATP, as occurs in muscle.glycolyt´ic
Glycolysis The pathway in which a cell breaks down glucose into energy. Mentioned in: Pyruvate Kinase Deficiency 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. Also called Embden-Meyerhof pathway. See also aldolase, citric acid cycle, lactic acid. 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.

Lactate dehydrogenase (LDH) is the last enzyme of the glycolytic pathway and catalyzes the conversion of pyruvate to lactate (forward; LDHf) or lactate to pyruvate (reverse; LDHr). When oxygenation reaches low critical levels, conservative strategies favor reversible inhibition of the glycolytic pathway, coupled with additional substrate-level phosphorylations (Hochachka & Somero 2002). Common sense dictates that without proper blood flow, there will not be efficient delivery of oxygen to tissues, and without oxygen, tissues are forced through glycolytic pathways to maintain function. |
