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.

  • Succinate, S ( type S-pathway to Q).
  • Addition of cytochrome c yields a test for integrity of the mtOM. Stimulation by added cytochrome c would indicate an injury of the mtOM and limitation of respiration in the preceding state without added c due to loss of cytochrome c. Typically, cytochrome c is added immediately after the earliest ADP-activation step (P, OXPHOS-capacity with saturating [ADP]).
  • OXPHOS capacity, P (with saturating [ADP]), active OXPHOS state.
