Disorders of the electron transport chain
Journal of Inherited Metabolic Disease, 1996SummaryDefects in a pathway as complex as the electron transport chain cause a variety of clinical abnormalities, which vary from fatal lactic acidosis in infancy to mild muscle disease in adults. The primary defect may reside in the nucleus or the mitochondrial genome.

Regulation of the photosynthetic electron transport chain
Planta, 1999The regulation of electron transport between photosystems II and I was investigated in the plant Silene dioica L. by means of measurement of the kinetics of reduction of P(700) following a light-to-dark transition. It was found that, in this species, the rate constant for P(700) reduction is sensitive to light intensity and to the availability of CO(2).

Pseudogenes and The Electron Transport Chain
2007With the advent of easy access to the human genome sequence, molecular biology techniques to target respirome-specific genes have begun to be exploited in the study of human disorders and in particular human cancers. In some recent publications it would appear that some investigators have inappropriately targeted pseudogenes rather than functional ...

Analyzing electron transport chain supercomplexes
2020This review focuses on three independent and complementary approaches to obtain information on the combined function of respiratory complexes when present in different structural situations, either as individual complexes or when superassembled with other complexes.

This chapter considers electron transport chains. Two of the most fundamental metabolic processes, aerobic respiration and photosynthesis, which play such a critical role in maintaining life on Earth, require a succession of electron transfers. In both processes the electron transfers take place in membrane-localized electron transport chains that ...

Electron transport chain in a thermotolerant yeast
Journal of Bioenergetics and Biomembranes, 2017Yeasts capable of growing and surviving at high temperatures are regarded as thermotolerant. For appropriate functioning of cellular processes and cell survival, the maintenance of an optimal redox state is critical of reducing and oxidizing species.

Mobility in the mitochondrial electron transport chain
Biochemistry, 1985The role of lateral diffusion in mitochondrial electron transport has been investigated by measuring the diffusion coefficients for lipid, cytochrome c, and cytochrome oxidase in membranes of giant mitoplasts from cuprizone-fed mice using the technique of fluorescence redistribution after photobleaching (FRAP).

The Electron Transport Chain and Carcinogenesis
2008Major metabolic changes that affect the balance between respiration and glycolysis occur during carcinogenesis. It is therefore not surprising that it has long been suggested that abnormal activity of the mitochondrial electron transfer chain could play a role in the underlying pathophysiologic process.

Regulation of Mitochondrial Electron Transport Chain Assembly
Journal of Molecular Biology, 2018Mitochondrial function depends on the correct synthesis, transport, and assembly of proteins and cofactors of the electron transport chain. The initial idea that the respiratory chain protein complexes (RCCs) were independent structures in the inner mitochondrial membrane evolved after the identification of higher quaternary structures called ...

Electron Transport Chain Defects in Heart Failure
Heart Failure Reviews, 2002In recent years, the possibility that disorders of cardiac metabolism play a role in the mechanisms that lead to ventricular dilatation and dysfunction in heart failure has attracted much attention. Electron transport chain is constituted by a series of multimeric protein complexes, located in the inner mitochondrial membranes, whose genes are ...
