[[File:SUIT-catg FNSGp.jpg|right|300px|Q-junction]] The '''Q-junction''' is a junction for [[convergent electron flow]] in the [[Electron transfer-pathway]] (ET-pathway) from type N substrates and mt-matix dehydrogenases through [[Complex I]] (CI), from type F substrates and FA oxidation through [[electron-transferring flavoprotein complex]] (CETF), from succinate (S) through [[Complex II]] (CII), from glycerophosphate (Gp) through [[glycerophosphate dehydrogenase complex]] (CGpDH), from choline through [[choline dehydrogenase]], from dihydro-orotate through [[dihydro-orotate dehydrogenase]], and other enzyme complexes into the Q-cycle (ubiquinol/ubiquinone), and further downstream to [[Complex III]] (CIII) and [[Complex IV]] (CIV). The concept of the Q-junction, with the [[N-junction]] and [[F-junction]] upstream, provides the rationale for defining [[Electron transfer-pathway state]]s and [[categories of SUIT protocols]].e]]s and [[categories of SUIT protocols]]. +
