The stimulation of K+ and Na+ uptake by tris(hydroxymethyl)arninomethane (Tris) in freshly cut beetroot tissue slices was inhibited by D.glucosamine. This effect could be fully reversed by further addition of Dglucose, and the reversal was specific for D.glucose. Tris caused a marked increase in glucose uptake from a dilute glucose solution (5 X 10-'M). The stimulation of glucose uptake was further enhanced by the presence of N a +.
