ATP captures the chemical energy released by the combustion of nutrients and transfers it to reactions that require energy, e.g. An important role was that played by the 1953 Nobel laureate in Medicine Fritz Lipmann when he during the years 1939-41 showed that ATP is the universal carrier of chemical energy in the cell and coined the expression “energy-rich phosphate bonds”.ĪTP functions as a carrier of energy in all living organisms from bacteria and fungi to plants and animals including humans. Its structure was clarified some years later and in 1948 the Scottish Nobel laureate of 1957 Alexander Todd synthesised ATP chemically. The German chemist Karl Lohmann discovered ATP in 1929. ATP – the universal energy carrier in the living cell This enzyme maintains the balance of sodium and potassium ions in the living cell.īoth enzymes are bound to membranes in the cell and linked with the transport of ions through these – but for different reasons. Skou receives his half of the prize for the discovery of the enzyme sodium, potassium-stimulated adenosine triphosphatase (Na +, K + -ATPase). Walker and his co-workers have established the structure of the enzyme and verified the mechanism proposed by Boyer. Boyer and his co-workers have proposed, on the basis of biochemical data, a mechanism for how ATP is formed from adenosine diphosphate (ADP) and inorganic phosphate. Walker receive half the prize for their work on how the enzyme ATP synthase catalyses the formation of ATP. The three laureates have performed pioneering work on enzymes that participate in the conversion of the “high-energy” compound adenosine triphosphate (ATP).
