Altered mitochondrial metabolism is the underlying basis for the increased sensitivity in the
aged heart to stress. The aged heart exhibits impaired metabolic flexibility, with a decreased …

The mitochondrion is a major source of reactive oxygen species (ROS). Superoxide (O2•−)
is generated under specific bioenergetic conditions at several sites within the electron …

Extensively revised, the fourth edition of this highly successful book takes into account the
many newly determined protein structures that provide molecular insight into chemiosmotic …

Keilin's classic paper of 1925 [Keilin (1925) Proc. R. Soc. London Ser. B 100, 129–151],
achieved with simple, but elegant, techniques, describes the cytochrome components of the …

▪ Abstract The bc 1 complexes are intrinsic membrane proteins that catalyze the oxidation of
ubihydroquinone and the reduction of cytochrome c in mitochondrial respiratory chains and …

The chapter provides a review of the state of art of the oxidative phosphorylation system in
mammalian mitochondria. The sections of the paper deal with:(i) the respiratory chain as a …

▪ Abstract The cytochrome bc complexes represent a phylogenetically diverse group of
complexes of electron-transferring membrane proteins, most familiarly represented by the …

▪ Abstract Enzymes of the mitochondrial respiratory chain serve as proton pumps, using the
energy made available from electron transfer reactions to transport protons across the inner …

Regulation of photosynthetic electron transport at the level of the cytochrome b 6 f complex
provides efficient performance of the chloroplast electron transport chain (ETC). In this …

This review is focused on pH-dependent mechanisms of regulation of photosynthetic
electron transport and ATP synthesis in chloroplasts. The light-induced acidification of the …
