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).
2Rot	SL(n)	S	CII	1S;2Rot 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). Succinate pathway control state (S-pathway) after inhibiting CI with rotenone, which also inhibits the F-pathway.
3D	SP	S	CII	1S;2Rot;3D Succinate, S ( type S-pathway to Q). OXPHOS capacity P (with saturating [ADP]), active OXPHOS state.
4Ama	ROX			1S;2Rot;3D;4Ama 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).
