Step State Pathway Q-junction Comment - Events (E) and Marks (M)
1PM PML(n) N CI 1PM
2D PMP N CI 1PM;2D
2c PMcP N CI 1PM;2D;2c
  • NADH-linked substrates (type N-pathway to Q).
  • Addition of cytochrome c yields a test for integrity of the mtOM. Stimulation by added cytochrome c would indicate an injury of the mtOM and limitation of respiration in the preceding state without added c due to loss of cytochrome c. Typically, cytochrome c is added immediately after the earliest ADP-activation step (P, OXPHOS-capacity with saturating [ADP]).
  • OXPHOS capacity, P (with saturating [ADP]), active OXPHOS state.
3U PME N CI 1PM;2D;3U
4S PMSE NS CI&II 1PM;2D;3U;4S
  • Respiratory stimulation by simultaneous action of type N substrates & succinate, with convergent electron flow in the NS-pathway for reconstitution of TCA cycle function.
  • Noncoupled electron transfer state, ET-state, with ET-capacity, E.
5Rot SE S CII 1PM;2D;3U;4S;5Rot
6Ama ROX 1PM;2D;3U;4S;5Rot;6Ama
  • Rox is the residual oxygen consumption in the ROX state, due to oxidative side reactions, estimated after addition of Antimycin A (inhibitor of CIII). Rox is subtracted from oxygen flux as a baseline for all respiratory states, to obtain mitochondrial respiration (mt).
