## Abstract In glucose exchange transport into red blood cells the rate of glucose uptake showed two pH dependent maxima, with the larger at approximately pH 7.5 and the smaller one at pH 3. In the studied pH range the relation between the rate of glucose uptake and the substrate concentration fol

Abstract
The thermodynamic parameters ΞHΒ°, ΞFΒ°, ΞSΒ° and the pH dependence of the interaction between steroids and the glucose carrier in human erythrocytes have been studied. The results indicate that, according to the structure of the steroids, hydrophilic as well as hydrophobic bonds can be involved in the association. For the binding of the Cβ21βsteroids to the carrier the polarity rule has been observed to be valid. On the basis of the thermodynamic parameters it has been found that in the association process of the steroids with the carrier, simultaneous randomization of ordered water molecules is important.

## Abstract The temperature dependence of the uptake of glucose by exchange transport is investigated at two pH values (7.5 and 5). The Arrhenius's energy of activation, the heat of activation, the free energy of activation and the entropy of activation are calculated. The parameters are different
## Abstract Alcohols inhibit the exchange transport of glucose in human erythrocytes. Comparing the inhibition by monohydroxyβalcohols, which have different distribution coefficients between medium and membrane, shows that the degree of inhibition depends mainly upon the concentration of the alcoho
## Abstract Local anesthetics inhibit the exchange transport of glucose in human erythrocytes. All compounds tested showed a competitive inhibition except lidocaine and baycaine causing a nonβcompetitive one. Moreover the transport system can bind two inhibitor molecules to one transport site as de
To reveal the role of the band 3 anion transport protein of the erythrocyte membrane in drug transport through the membrane, the possible effects of inhibitors of anion transport on the permeability of some anionic drugs were examined. The amounts of these drugs that permeated varied markedly with t
