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.
ce1Glc	ROUTINE			ce1;ce1Glc ROUTINE respiration in the physiological coupling state R. Externally added permeable substrates could contribute to this respiratory state. Glucose is added to test Crabtree effect.
ce2(Omy)	L			ce1;ce1Glc;ce2Omy Non-phosphorylating resting state (LEAK state); LEAK-respiration, L(Omy), after blocking the ATP synthase with oligomycin.
ce3U	E			ce1;ce1Glc;ce2Omy;ce3U Noncoupled electron transfer state, ET state, with ET capacity E.
ce4Ama	ROX			ce1;ce1Glc;ce2Omy;ce3U;ce4Ama 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.
