[Oxidation of Krebs cycle substrates by Eurytrema pancreaticum mitochondria]

From tissues of E. pancreaticum were isolated mitochondria capable to swell under the effect of some factors. The intensive oxidation of succinate, isocitrate, cisaconitate, oxalacetate and alpha-ketoglutarate by mitochondria and less intensive one of malate, fumarate, citrate and pyruvate were shown. NAD caused the rise in oxidation intensity of isocitrate, cis-aconitate, oxalacetate, alpha-ketoglutarate, malate, fumarate and pyruvate while NADP--of isocitrate and citrate.
