Metabolism and Sodium Transport in the Isolated Rat Intestine

Nature volume 210, pages 307–308 (1966)Cite this article

Abstract

IT is well known that sodium, is actively transported through many biological membranes1–7 and several authors have also determined the amount of energy necessary for this8–18. The ratio between energy and transported sodium, has usually been calculated by determining the increase of oxygen consumption (or lactic acid production) and the associated increase of sodium transport. These increases were obtained by modifying the quantity of available sodium8,10,11,15,16, or by stimulating the sodium pump (posthypophyseal hormones)8,9 or by modifying the quantity of chemical energy at the disposal of the membrane13,26. In this work the third procedure has been followed, and results are reported concerning the relationship between the sodium transport, the oxygen consumption and the lactic acid production in the isolated rat intestine perfused in vitro with different concentrations of glucose.
