[The isolation of mitochondria fron different sections of the small intestine and their functional characteristics].
High level of oxygen consumption is specific for the proximal part of small intestine in rats, particularly when mitochondria are active and when oxidative phosphorylation is uncoupled by 2.4 Dinitrophenol. High degree of coupling seems to exist in this part of the intestine. The intensity of substrate oxidation, activity of multienzyme systems of respiratory chains, and the ATP formation velocity are considerably lower in the distal part of the small intestine than in the proximal and medial ones.
