Quinone 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 pathway
