Chinoform glucuronide (5-chloro-7-iodo-8-quinolyl-β-D-glucuronic acid) had no uncoupling action. Whole body irradiation of rabbits or rats with X-rays or Co60 γ-rays causes uncoupling of oxidative phosphorylation in thymus mitochondria, which is not prevented by the prior administration of AET. Whole body irradiation was not found to affect oxidative phosphorylation in liver or mouse ascites cell mitochondria. The radiation lesion can be repaired in vitro by the addition of cytochrome c Cheng S, Clancy CJ, Zhang Z, Hao B, Wang W, Iczkowski KA, Pfaller MA, Nguyen MH (2007) Uncoupling of oxidative phosphorylation enables Candida albicans to resist killing by phagocytes and persist in tissue.

Article; CAS; Google Scholar Following the pioneer studies of Mitchell and Moyle (1) it is now generally accepted that there exists a correlation between protonophoric effects and uncoupling of oxidative phosphorylation. However conclusive evidence has never been reported that the uncoupling is exclusively due to the increase of membrane conductance for protons. Under non-phosphorylating conditions a high proton transmembrane gradient inhibits the rate of oxygen consumption mediated by the mitochondrial respiratory chain (state IV). Slow electron transit leads to production of reactive oxygen species (ROS) 2021-04-08 · The mechanism of PCBC uncoupling of mitochondrial oxidative phosphorylation has been investigated using isolated rabbit renal cortical mitochondria (RCM). PCBC increased state 4 respiration of RCM respiring on pyruvate/malate or succinate in a concentration (10-100 microM)- and time (1-5 min)-dependent manner. FCCP compromises oxidative phosphorylation in CECs. To assess the effects of uncoupling the electron transport chain in CECs, Seahorse XFe96 Bioanalyzer with the Mito-Stress Test was utilized.

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.

Uncoupling of oxidative phosphorylation

Fatty acid: Uncoupling; ATP/ADP antiporter; Thermogenin !. FATTY ACID-K4EDIATED THERMOREGU- LATORY UNCOUPLING In 1960 we proposed that uncoupling of oxidative phosphorylation is a mechanism of the urgent heat production by warm-blooded animals when the ambient temperature strongly decreases [1] (see also [2]).

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.

Briefly, the injection of different compounds, sequentially, disrupts the ETC. 2021-02-25 An uncoupling protein (UCP) is a mitochondrial inner membrane protein that is a regulated proton channel or transporter.An uncoupling protein is thus capable of dissipating the proton gradient generated by NADH-powered pumping of protons from the mitochondrial matrix to the mitochondrial intermembrane space.The energy lost in dissipating the proton gradient via UCPs is not used to do Uncouplers of oxidative phosphorylation. Uncouplers of oxidative phosphorylation in mitochondria inhibit the coupling between the electron transport and phosphorylation reactions and thus inhibit ATP synthesis without affecting the respiratory chain and ATP synthase (H(+)-ATPase).

PCP because it enters a dormant state at high PCP concentrations, thus not wasting energy that would be lost due to 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.
