Summary:Polarographic studies have been made on the respiratory activity of isolated mitochondria of the trematode F. hepatica. Respiratory chain transferring electrons to oxygen and which is sensitive to cyanide was found in the mitochondria. Certain coupling between respiration and phosphorylation was observed. Intact mitochondria of the trematode exhibit the respiratory control although its level is significantly lower than that in the mitochondria from rat liver. The existence of an alternative respiratory chain was demonstrated in which electron transport is not associated with ATP synthesis.
