Glycolysis is the metabolic pathway that converts glucose into pyruvate.
Glycolysis (from glycose, an older term for glucose + -lysis degradation) is the metabolic pathway that converts glucose C 6 H 12 O 6, into pyruvate, CH 3 COCOO − + H + . Glycolysis occurs in most organisms in the cytosol of the cell. The most common type of glycolysis is the Embden–Meyerhof–Parnas (EMP pathway) , which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas. Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. Glycolysis is a metabolic pathway that takes place in the cytosol of cells in all living organisms. This pathway can function with or without the presence of oxygen. In humans, aerobic conditions produce pyruvate and anaerobic conditions produce lactate. The metabolic pathway of glycolysis converts glucose to pyruvate by via a series of intermediate metabolites. Each chemical modification (red box) is performed by a different enzyme. Steps 1 and 3 consume ATP (blue) and steps 7 and 10 produce ATP (yellow). Glycolysis occurs in most organisms in the cytosol of the cell. The most common type of glycolysis is the Embden–Meyerhof–Parnas (EMP pathway) , which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas. Most cancer cells exhibit increased glycolysis and use this metabolic pathway for generation of ATP as a main source of their energy supply. This phenomenon is known as the Warburg effect and is considered as one of the most fundamental metabolic alterations during malignant transformation.  Glycolysis is an oxygen independent metabolic pathway, meaning that it does not use molecular oxygen (i.e. atmospheric oxygen) for any of its reactions. However the products of glycolysis (pyruvate and NADH + H +) are sometimes disposed of using atmospheric oxygen. Glycolysis occurs in most organisms in the cytosol of the cell. The most common type of glycolysis is the Embden–Meyerhof–Parnas (EMP pathway) , which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas. Again this reaction is endothermic and thus requires energy from a coupled reaction with ATP. ATP is used by being hydrolyzed to ADP and phosphate giving off energy and the phosphate for reaction with the glucose for a net loss of ATP in the overall glycolysis pathway. Hydrolysis: ATP + H 2. P = PO 4 -3; ATP = adenine triphosphate;ADP = adenine diphosphate. The overall reaction of glycolysis which occurs in the cytoplasm is. represented simply as: C 6 H 12 O 6 + 2 NAD + 3 (C=O)COOH + 2 ATP + 2 NADH + 2 H +. At this time, concentrate on the fact that glucose with six carbons is converted into two pyruvic acid molecules with three carbons each. Medical Definition of GLYCOLYSIS. : the enzymatic breakdown of a carbohydrate (as glucose or glycogen) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP—called also Embden-Meyerhof pathway. — gly·co·lyt·ic \ˌglī-kə-ˈlit-ik\ adjective. : the enzymatic breakdown of a carbohydrate (as glucose) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP. — gly·co·lyt·ic \ˌglī-kə-ˈli-tik\ adjective. ADVERTISEMENT. Glycolysis. The pathway in which a cell breaks down glucose into energy. Mentioned in: Pyruvate Kinase Deficiency. 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. 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.
