Mitochondrial Complex I (NADH:ubiquinone oxidoreductase) is the largest enzyme complex of the respiratory chain, essential for cellular energy production. This multiprotein assembly couples the ...

Mammalian mitochondrial electron transport chain complexes are the most important and complicated protein machinery in mitochondria. Although this system has been studied for more than a century, its ...

A study has revealed that protons and reactive oxygen species mediate long-distance charge transport in the mitochondrial respiratory chain — a fundamental process in cellular respiration in ...

Tiny biological batteries known as mitochondria keep the body's cells running smoothly, and their gradual decline is linked to a wide range of age-related diseases. Now scientists think they have ...
