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.
(ce2Omy)	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 is optional depending on the experimental question to resolve.
ce3U	E			cce1;(ce2Omy);ce3U Uncoupler titration (avoiding inhibition by high uncoupler concentrations) to obtain electron transfer (ET) capacity E (noncoupled ET-state). Test for limitation of OXPHOS capacity P by the phosphorylation system (ANT, ATP synthase, phosphate transporter) relative to ET capacity E in mt-preparations: E-P control efficiency and E-L coupling efficiency. In living cells: E-R control efficiency and E-L coupling efficiency. Noncoupled electron transfer state, ET state, with ET capacity E.
ce4Rot	ROX			ce1;(ce2Omy);ce3U;ce4Rot 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.
ce5DMSO	ROX			ce1;(ce2Omy);ce3U;ce4Rot;ce5DMSO 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.
ce6DMSO	ROX			ce1;(ce2Omy);ce3U;ce4Rot;ce5DMSO;ce6DMSO 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.
ce7Ama	ROX			ce1;(ce2Omy);ce3U;ce4Rot;ce5DMSO;ce6DMSO;ce7Ama 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.

Strengths and limitations

Work in progress

• The SUIT-003 O2 ce D061 is a cell coupling control protocol. The total cell count (N_ce) is the sum of viable cells (N_vce) and dead cells (N_dce).
• CIV activity can also be measured after the cell viability test module.

- The addition of oligomycin has to be carefully tested to avoid inhibitory effects in the evaluation of the ET-capacity.

- Careful washing is required after the experiment to avoid carry-over of inhibitors and uncoupler.
