Redox control of mitochondrial functions.
Redox reactions and electron flow through the respiratory chain are the hallmarks of mitochondria. By supporting oxidative phosphorylation and metabolite transport, mitochondrial redox reactions are of central importance for cellular energy conversion. In the present review, we will discuss two other aspects of the mitochondrial redox state: (i) its control of mitochondrial Ca2+ homeostasis, and (ii) the intramitochondrial formation of reactive oxygen or nitrogen species that strongly influence electron flow of the respiratory chain.
