Data obtained using antimycin and myxothiazol, both of which stimulated the release of H2O2 from insect mitochondria, lead to the conclusion that glycerophosphate dehydrogenase is a source of H2O2.
Other respiratory inhibitors, antimycin, myxothiazol, and rotenone were used with insect mitochondria.

Results are interpreted to suggest that partial inhibition of cytochrome c oxidase activity can lead to the stimulation of mitochondrial H2O2 production in the housefly at site (s) other than NADH dehydrogenase and ubisemiquinone/cytochrome b region; a possible source may be glycerophosphate dehydrogenase.
H2O2 release by mitochondria, inhibited with rotenone and antimycin A, was greatly increased upon supplementation with alpha-glycerophosphate; however, the further addition of KCN or myxothiazol, to such preparations, caused a depression of H2O2 generation.
