Abstract
One mM KCN fully inhibited the activity of cytochrome oxidase and the succinateoxidation in corn mitochondris, while the oxygen uptake of α-ketoglutarate was not affectedat all. In the latter case, a very strong inhibition could occur when both KCN and KSCNwere simultaneously present. After cyanide inhibition of succinate oxidation, the oxygen uptake could subsequentlyreappear by addition of α-ketoglutarate, but at that time the cytochromes c and a stillremained in their reduced state. In contrast to the cyanide-resistance,α-ketoglutarate oxidation was inhibited by antimycin A. It has been suggested that cytochromes a and c are not involved in the cyanide-insensi-tive alternative pathway in corn mitochondria and the branching point is located on the mainrespiratory chain after cytochrome b instead of before it.
