Fig. 1From: Using a chimeric respiratory chain and EPR spectroscopy to determine the origin of semiquinone species previously assigned to mitochondrial complex IQuinone cycling in AOX-SMPs during NADH oxidation. (Top) Flow diagram showing the routes of quinol (QH2) production and oxidation and their inhibitor sensitivities. Radicals (•) indicate expected formation of semiquinones. (Bottom) AOX-SMPs support NADH:O2 turnover through both the canonical chain and the complex I-AOX pathwayBack to article page
