Steps and respiratory states

Step State Pathway Q-junction Comment - Events (E) and Marks (M)


ce1 ROUTINE ce1
  • ROUTINE respiration in the physiological coupling state R. Externally added permeable substrates could contribute to this respiratory state.
ce2(Omy) L(Omy) ce1;ce2Omy
  • Non-phosphorylating resting state (LEAK state); LEAK-respiration, L(Omy), after blocking the ATP synthase with oligomycin.
  • The addition of oligomycin or its carrier (EtOH) is optional depending on the experimental question to resolve. If we add only the carrier we do not reach LEAK state and we will evaluate if the EtOH alters the ROUTINE state.
ce3U E ce1;ce2Omy;ce3U
ce* ROX ce1;ce2Omy;ce3U;ce*
  • Rox is the residual oxygen consumption in the ROX state, due to oxidative side reactions, estimated either after inhibition of CIII (e.g. antimycin A, myxothiazol), CIV (e.g. Cyanide) or in the absence of endogenous fuel-substrates. Rox is subtracted from oxygen flux as a baseline for all respiratory states, to obtain mitochondrial respiration.
