Abstract: | Dicarboxylate transport was studied in the inner membrane matrix fraction (mitoplasts) and compared to that in intact rat-liver mitochondria from which the former was obtained.It is concluded that, kinetics of dicarboxylate exchange measured in mitoplasts, are very similar to those observed with mitochondria. These results would indicate that the preparation technique preserves the integrity of the inner membrane and that neither the outer membrane nor the components of the peripheral space affect these results. |
