Example of respiration of permeabilized cardiomyocytes. Representative example recorded at 10°C in the absence of creatine showing the respiration rate of permeabilized trout cardiomyocytes (CM) during stepwise increases in ADP-concentration as indicated. Note that the respiration rate was relatively stable at each step of the ADP-titration, that cytochrome c did not increase respiration rate, and that atractyloside brought respiration rate down to the same level as the basal respiration rate before addition of ADP.
