Steps and respiratory states

Step	State	Pathway	Q-junction	Comment - Events (E) and Marks (M)
1S	SL(n)	S	CII	1S Succinate, S ( type S-pathway to Q). Non-phosphorylating resting state (LEAK state); LEAK respiration L(n) in the absence of ADP, ATP, AMP (no adenylates).
2D	SP	S	CII	1S;2D Succinate, S ( type S-pathway to Q). OXPHOS capacity P (with saturating [ADP]), active OXPHOS state.
3P	NSP	NS	CI&II	1S;2D;3P Respiratory stimulation by simultaneous action of type N substrates & succinate, with convergent electron flow in the NS-pathway for reconstitution of TCA cycle function. OXPHOS capacity P (with saturating [ADP]), active OXPHOS state.
4Rot	SP	S	CII	1S;2D;3P;4Rot Succinate, S ( type S-pathway to Q). OXPHOS capacity P (with saturating [ADP]), active OXPHOS state. Succinate pathway control state (S-pathway) after inhibiting CI with rotenone, which also inhibits the F-pathway.
5Ama	ROX			1S;2D;3P;4Rot;5Ama 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).
