Complex I (CI) is the segment of the electron transport system (integral enzyme of the inner mitochondrial membrane) responsible for electron transfer from NADH to ubiquinone. CI is sensitive to different pathologies, particularly to oxidative stress, which is involved in ischemia-reperfusion injury, anoxia/ reoxygenation, aging, etc (Kuznetsov et al 2004; Rouslin & Millard 1981; Rouslin & Ranganathan, 1983; Rouslin, 1983). For the assessment of CI activity, among the ubiquinone isoprenologs, it is most convenient to use ubiquinone-1 (CoQ1) as electron acceptor, because of its relative water solubility. Importantly, CoQ1 yields one of the lowest rotenone insensitive rates and a high enzymatic rate. It is, therefore, the best electron acceptors for the CI assay. | Complex I (CI) is the segment of the electron transport system (integral enzyme of the inner mitochondrial membrane) responsible for electron transfer from NADH to ubiquinone.

Abstract: Kuznetsov AV, Gnaiger E. Laboratory protocol: Complex I (NADH:Ubiquinone Oxidoreductase, EC 1.6.5.3). Mitochondrial membrane enzyme. Mitochondr Physiol Network 08.15.
Complex I (CI) is the segment of the electron transport system (integral enzyme of the inner mitochondrial membrane) responsible for electron transfer from NADH to ubiquinone. CI is sensitive to different pathologies, particularly to oxidative stress, which is involved in ischemia-reperfusion injury, anoxia/ reoxygenation, aging, etc (Kuznetsov et al 2004; Rouslin & Millard 1981; Rouslin & Ranganathan, 1983; Rouslin, 1983). For the assessment of CI activity, among the ubiquinone isoprenologs, it is most convenient to use ubiquinone-1 (CoQ1) as electron acceptor, because of its relative water solubility. Importantly, CoQ1 yields one of the lowest rotenone insensitive rates and a high enzymatic rate. It is, therefore, the best electron acceptors for the CI assay.
