Krebs, Hans Adolf
Sir Hans Adolf Krebs (1900–1981), an English biochemist who received the 1953 Nobel Prize in Physiology or Medicine, awarded jointly to him and to F. A. Lipmann, for their description of the cycle of chemical reactions that proved to be the major source of energy in living organisms. The citric acid cycle, or the Krebs cycle, is a series of chemical reactions of central importance in all living cells that utilize oxygen as part of cellular respiration. The breakdown of glucose into carbon dioxide and water is a complex set of chemical interconversions called carbohydrate catabolism; the Krebs cycle is the second of three major stages in the process, occurring between glycolysis and oxidative phosphorylation.
