Comparison between active transport of T1+, K+ and Rb+ across the isolated short-circuited frog skin.
Active transport of T1+ by frog skin was compared with transport of K+ and Rb+. T1+ was transported actively (using a Na,K-ATPase) by the epithelium and the adrenaline-stimulated glands. In the epithelium, K+, T1+ and Rb+ competed for transport in the ratio 1:1.7:0.9; in the glands the ratio was 1:1:1.
