[Effect of various inhibitors on oxidative activity and ultrastructure of rat liver mitochondria].

Parallel studies concerning the influence of some inhibitors on electron transfer, and ultrastructural aspects of rat liver mitochondria led to the conclusion that metabolic activity and mitochondrial ultrastructure are closely linked ; when mitochondria oxidize succinate, their configuration change from the "condensed" to the "orthodox" state ; this change does not occur if the oxidation is inhibited.
