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.
This dissociation of oxidation and phosphorylation is termed "uncoupling". Many of the substances which have been shown to uncouple phosphorylation from oxidation are drugs which have been employed in experimental pharmacology and therapeutics. 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). Miscellaneous compounds are known to be uncouplers, but wea … 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).

They are able to induce mild uncoupling, thus increasing the rate of respiration and decreasing the pro-duction of reactive oxygen species (ROS) (24-27). A UCP was also detected recently in C. parapsilosis (28). Therefore, it is of great interest to study C. albicans UCP in order to oxidative phosphorylation in mitochondria andprokar-yoticcells, it is suppliedbytherespiratorychain.

Europe PMC Mitochondrial uncoupling proteins (UCPs) in the inner membrane mediate uncoupling of oxidative phosphorylation through a proton-transport mechanism that allows the return of protons to the oxidative phosphorylation in mitochondria and prokar-yotic cells, it is supplied by the respiratory chain. Thus ATP is synthesized by coupling two reactions, electron Structure and uncoupling activities (maximal stimulation of stage 4 respiration of isolated rat liver mitochondria) of representative weakly acidic uncouplers (5,25).

2,4-Dinitrophenol is an uncoupling agent; oligomycin blocks the ATP synthesis reaction itself. Therefore, 2,4-dinitrophenol will: A) allow electron transfer in the presence of oligomycin. B) allow oxidative phosphorylation in the presence of oligomycin. The Mechanism of Coupling in Oxidative Phosphorylation Several mechanisms have been proposed to account for the coupling of electron transport and ATP production. The mechanism that served as the point of departure in all discussions is chemiosmotic coupling, which was later modified to include a consideration of conformational coupling.
