摘要：

The external application of inhibitors of glycolysis in the presence of KCN shows a lethal effect on plasmodia of Physarum polycephalum. However, .alpha.-ketoglutarate, but not succinate, maintains the contraction-relaxation cycle of plasmoidal actomyosin in spite of the fact that glycolysis and cytochrome oxidase are inhibited. The oscillations supported by ketoglutarate disappear in the presence of SHAM [salicylhydroxamic acid], an inhibitor of alternative oxidase. There results imply the existence of KCN-resistant, alternative pathway of electron transport in the mitochondria of Physarum polycephalum.
