Abstract: Mitoehondria from different plants, such as corn, wheat, mung bean and cucumher, were studied with respect to relative rate of oxidation of different substrates. It was found that the degree of cyanide-sensitive respiration in isolated mitochondria from different plants was dependent upon the nature of substrates. With α-ketoglutarate as the electron donor, resistance to cyanide of the respiratory chain was higher than that with other substrates. In the case of adding α-ketoglutarate, the mitochondrial oxidation inhibited by cyanide could be partially recovered, where as the inhibition of azide could not be recovered. This fact showed that the alternative terminal oxidases may not exist when keto acids was used as substrates because cyanide was ineffective as an inhibitor owing to removal the cyanide by eyanohydrin fomation.
