Description
The Q-junction is a junction for convergent electron flow in the electron transfer system (ETS) from Complex I (CI), Complex II (CII), electron-transferring flavoprotein complex (CETF), glycerophosphate dehydrogenase complex (CGpDH), choline dehydrogenase and other enzyme complexes into the Q-cycle (ubiquinol/ubiquinone), and further to Complex III (CIII).
Abbreviation: Q
Reference: Gnaiger 2009 Int J Biochem Cell Biol, Gnaiger 2014 MitoPathways
MitoPedia methods: Respirometry
MitoPedia O2k and high-resolution respirometry: "SUIT protocol" is not in the list (O2k hardware, DatLab, Oroboros QM, O2k-Open Support, O2k-Respirometry, O2k-FluoRespirometry) of allowed values for the "MitoPedia O2k and high-resolution respirometry" property.

Convergent CI&II-linked electron flow at the Q-junction, exerting an additive effect on flux, versus electron gaiting for separation of single input pathways (upper panel: Gnaiger 2009; lower panel: Hatefi 1962 J Biol Chem-XLII). From Fig. 1.5 in Gnaiger 2014 MitoPathways.
