  1. The number of experiments was 11 and 10 for the ZL and ZDF groups respectively. ZL: Zucker lean rats; ZDF: Zucker Diabetic fatty rats; CI: NADH:ubiquinone oxidoreductase; CII: succinate-ubiquinone oxido-reductase; CIII: ubiquinol-cytochrome-c reductase; CIV: cytochrome c oxidase; CI + III: NADH cytochrome c reductase; CII + III: succinate cytochrome c reductase; CS: citrate synthase. The results are expressed in mU/mg of proteins. *: significantly different.
