The membrane-bound electron transfer pathway (mET pathway) consists in mitochondria mainly of respiratory complexes CI, CII, electron transferring flavoprotein complex (CETF), glycerophosphate dehydrogenase complex (CGpDH), and choline dehydrogenase, with convergent electron flow at the Q-junction (Coenzyme Q), and the two downstream respiratory complexes connected by cytochrome c, CIII and CIV, with oxygen as the final electron acceptor. The mET-pathway is the terminal (downstream) module of the mitochondrial ET pathway and can be isolated from the ET-pathway in submitochondrial particles (SmtP).
