Correction: FADH₂ and S-pathway

FADH₂ is shown as the substrate feeding electrons into the membrane-ETS in the S-pathway. This requires correction: "Whereas reduced NADH is a substrate of Complex I linked to dehydrogenases of the TCA cycle and mt-matrix upstream of CI, reduced FADH₂ is a product of Complex II with downstream electron flow from CII to Q" (page 48 in Ref [1]. For details see Ref [2].
