Abstract
Uranyl ions have long been used as inhibitors of mono-accharide uptake by yeast. It is shown here that not only the rate of uptake but also the final distribution level is reduced. Monosaccharides transported by the specific carrier are most affected by 5×10−4 m uranyl nitrate while higher concentrations are less inhibitory. Monosaccharides transported by the universal carrier are affected by uranyl ions only to a lesser degree. Various hypotheses for the explanation of the effects are presented.
