- The ceCCP diagram may show the respiratory states directly (left) as an alternative to presenting the titration steps.
- Rot and Ama
- In this ceCCP, ROX is measured after titration of rotenone, antimycin A, or both in a single step. Validity of using rotenone only for inducing ROX in intact cells is evaluated by stepwise measurement of ROX after titration of rotenone (3Rot) followed by titration of animycin A (4ceAma).

- In this ceCCP, ROX is measured after stepwise titration of rotenone (ce4Rot) and antimycin A (ce5Ama). In many intact cells ROX measured after titration of rotenone (ce4Rot) is not or only slightly further inhibited by subsequent titration of animycin A (ce5Ama).

- 2ceOmy: LEAK (L; inhibition of ATPsynthase by 1 ΞΌg/ml oligomycin);
- 3ceU: ET-pathway (E; maximal stimulation by uncoupling of oxidative phosphorylation in four subsequent titrations of the uncoupler, U, FCCP (2.5β4 ΞΌM final concentration);
- 4ceRot: ROX (rotenone, Rot; residual oxygen consumption).
- 5ceAma: ROX (antimycin A, Ama; residual oxygen consumption). Modified after Huetter_2004_Biochem J.
