Oxidative phosphorylation and aging

Ageing Research Reviews, 2006
This review addresses the data that support the presence and contribution of decreased mitochondrial oxidative phosphorylation during aging to impaired cellular metabolism. Aging impairs substrate oxidation, decreases cellular energy production and increases the production of reactive intermediates that are toxic to the cell.

Uncouplers of oxidation phosphorylation

Pharmacology & Therapeutics, 1980
Abstract Numerous compounds, covering a broad range of chemical structures, selectively interfere with the mitochondrial mechanism for transforming energy derived from oxidative metabolism into regeneration of ATP. Within some chemical classes, structure-activity correlations have been useful.

Uncoupling of oxidative phosphorylation

Trends in Biochemical Sciences, 1976
Abstract The mechanism of oxidative phosphorylation is one of the most important problems in classical biochemistry, which has defied a solution for over thirty years. Uncouplers are powerful tools in the study of the coupling between oxidation and phosphorylation, and recent studies of photo-affinity labeling and equilibrium binding by uncouplers ...

Oxidative phosphorylation revisited

Biotechnology and Bioengineering, 2015
ABSTRACTThe fundamentals of oxidative phosphorylation and photophosphorylation are revisited. New experimental data on the involvement of succinate and malate anions respectively in oxidative phosphorylation and photophosphorylation are presented. These new data offer a novel molecular mechanistic explanation for the energy coupling and ATP synthesis ...

Oxidative phosphorylation in yeast II. An oxidative phosphorylation-deficient mutant

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1968
Abstract 1. Mitochondria from the mutant Saccharomyces cerevisiae DH 1 oxidized members of the tricarboxylic acid cycle, d (−)- and l (+)-lactates, ethanol, NADH, and N , N , N ′, N ′-tetramethyl- p -phenylenediamine with P/O ratios found in manometric experiments to be as low as 0.1 to 0.4. The low phosphorylation efficiency was not improved by

Mitochondrial Oxidative Phosphorylation

Angewandte Chemie International Edition in English, 1967
AbstractMitochondria can form ATP from ADP and inorganic phosphate, the required energy being supplied by respiration. This coupled process, which in sufficiently aerated normal animal cells furnishes the bulk of the cellular ATP, is termed oxidative phosphorylation.

A Theory of Oxidative Phosphorylation

Nature, 1958
EVIDENCE has been put forward that naphthoquinone derivatives take part in the phosphorylation of adenosine diphosphate to adenosine triphosphate by animal tissues1, chloroplasts2 and bacteria3. A similar role in phosphorylation by animal tissues has been proposed for α-tocopherylquinone4. It is therefore possible to formulate an earlier suggestion5 in

Oxidative Phosphorylation Disease Diagnosis [PDF]

Seminars in Neurology, 1999
ABSTRACT: Although the mtDNA encodes only 13 polypeptide subunits of the OXPHOS enzymes, approximately 1,000 proteins are estimated to be necessary for proper OXPHOS function. Over the past 10 years a wide variety of adult and pediatric OXPHOS diseases were found to be caused by or associated with mitochondrial DNA (mtDNA) mutations and nuclear DNA ...
