Its dysfunction is a primary contributor to metabolic disorders in insulin-sensitive tissues such as skeletal muscle and liver ( 2 - ) ( o site is an external quinol oxidation site on the intermembrane space side of the cytochrome bc 1 complex (complex III), where ubiquinol is oxidized and can form a semiquinone intermediate, providing a recognized site for ROS generation (as opposed to the internal Qi site, where quinone is reduced).Clinical biopsies reveal that complex I activity in T2DM skeletal muscle is reduced by approximately 40%, showing a significant positive correlation with systemic insulin sensitivity ( Consequently, ETC damage breaks the normal cycle of energy metabolism through excessive ROS accumulation, thereby activating inflammatory kinases, blocking the binding of IRS-1 to insulin receptors, and even inducing mtDNA damage while inhibiting OXPHOS gene transcription ( The generation of ROS by Complexes I and III, with subsequent activation of the JNK/IKK signaling pathway, is a consistently observed phenomenon across different experimental models
