[Effect of fasting on the content and transport of potassium ions in rat liver mitochondria]. 1982

E A Chukhlova, and L Iu Kudzina, and Iu V Evtodienko

The paper deals with the effect of fasting on the content and transport of potassium ions in the rat liver mitochondria as well as on oxidative phosphorylation. It is shown that the concentration of potassium ions in the mitochondria under fasting lowers by 20-30% at an average as compared to the control. The rate of potassium ions release from the mitochondria in the presence of DNP also lowers. It is found that the respiratory control ratio after 24-h fasting decreases and increases after 48-h fasting. Possible reasons of changes in the transport of potassium ions in the rat liver mitochondria in fasting are discussed.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p343-4) Liver Mitochondria,Liver Mitochondrion,Mitochondrion, Liver
D010085 Oxidative Phosphorylation Electron transfer through the cytochrome system liberating free energy which is transformed into high-energy phosphate bonds. Phosphorylation, Oxidative,Oxidative Phosphorylations,Phosphorylations, Oxidative
D011188 Potassium An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.
