pubmed:abstractText |
The active sugar and amino acid transport in the small intestine of the American leopard frog (Rana pipiens) and a species of European frog (Rana esculenta) decreases during the winter months. Parallel with this the (Na+, K+)-stimulated ("pump") ATPase activity is markedly depressed. No seasonal changes are observed in the intestine of the tropical bullfrog (Rana catesbeiana). It is assumed that the low pump-ATPase activity is caused by the hibernation of the frogs living in moderate or subtropical areas and is connected to a biological clock. The decreased active transport of non-electrolytes appears to be a consequence of the change of the ATPase activity.
