The effect of various concentrations of phlorizin and 2,4-dinitrophenol, plus the effect of oxygen deprivation on intestinal absorption of D-glucose was investigated. Paired segments of turtle (Chrysemys picta) small intestine in vitro were used. Preparations were incubated for one hour in a shaking water bath at 30°C in Krebs-Ringer-bicarbonate, with or without inhibitor. Phlorizin, in all concentrations used, was found to prevent uptake of glucose by the mucosal epithelium. Inhibition also occurred, in a lesser degree, with 2,4-dinitrophenol, and when the system was flushed with nitrogen instead of air.
