John W. Roseyear, M.D. f. The possibility that uncoupling of oxidative phosphorylation is a mechanism for development of acute hyperthermia during anesthesia 

From Wikipedia, the free encyclopedia An uncoupler or uncoupling agent is a molecule that disrupts oxidative phosphorylation in prokaryotes and mitochondria or photophosphorylation in chloroplasts and cyanobacteria by dissociating the reactions of ATP synthesis from the electron transport chain.

Uncoupling of oxidative phosphorylation (OXPHOS) by nonsteroidal antiinflammatory drugs can occur via protonophoretic activity and other mechanisms. At physiological pH, many carboxylic acids (or sulfonamides) are present as anions; they are protonated in the mitochondrial intermembrane space and can permeate into the matrix, where they are deprotonated again due to the inside negative membrane potential.

Uncoupling of oxidative phosphorylation in rat livermitochondria by general anesthetics. (membrane potential/ApH/membrane fluidity/ATPase/chemiosmosis) .

(membrane potential/ApH/membrane fluidity/ATPase/chemiosmosis) . Mitchell and Moyle (1) it is now generally accepted that there exists a correlation between protonophoric effects and uncoupling of oxidative phosphorylation. 13 Sep 2012 Mitochondrial Dysfunction: Uncoupling of Oxidative Phosphorylation Oxidative phosphorylation is a process by which the bond energy in  Energy produced by mitochondrial respiration is used for ATP synthesis by a complex mechanism referred to as “oxidative phosphorylation.” In addition to  product of oxidative phosphorylation. ADP-arsenate is unstable in water solution. It spontaneously decom- poses to ADP and arsenate. Thus uncoupling occurs. A number of substances are able to alter this relationship by depressing the formation of high-energy bonds without depressing simultaneously the oxygen  30 Apr 2019 There are drugs that inhibit mitochondrial oxidative phosphorylation, like carbon monoxide2, hydrogen sulfide3, and of course, cyanide.

The regulated uncoupling of oxidative phosphorylation is a biologically useful means of generating heat. The uncoupling of oxidative phosphorylation is a means of generating heat to maintain body temperature in hibernating animals, in some newborn animals (including human beings), and in mammals adapted to cold. An uncoupler or uncoupling agent is a molecule that disrupts oxidative phosphorylation in prokaryotes and mitochondria or photophosphorylation in chloroplasts and cyanobacteria by dissociating the reactions of ATP synthesis from the electron transport chain. The result is that the cell or mitochondrion expends energy to generate a proton motive force, but the proton motive force is dissipated before the ATP synthase can recapture this energy and use it to make ATP. Uncouplers are capable of tran Inhibitors and UnCouplers of Oxidative Phosphorylation Respiratory Inhibitors. The ETC chain contains 4 complexes (I, II, III and IV) that participate in the transfer of Inhibitors of Electron Transport.
