Steps and respiratory states

Step	State	Pathway	Q-junction	Comment - Events (E) and Marks (M)
0DTPA				DTPA is an iron chelator, which decreases the chemical fluorescence background created by the Amplex UltraRed assay. Administration of DTPA into the O2k-chamber is recommended before all other chemicals because the iron chelation capacity of the compound is time-dependent (approx. 10-15 min). However, the experiments can be carried out in the absence of DTPA.
0SOD				SOD or superoxide dismutase converts the anion superoxide released by the mitochondria into H2O2, making it accessible to the Amplex UltraRed assay.
0HRP				HRP or horseradish peroxidase catalyses the conversion of Amplex UltraRed and H2O2 towards the fluorescent resorufin.
0AmR				AmR or Amplex UltraRed forms resorufin with H2O2 catalysed by horseradish peroxidase HRP.
