... ion transport Na + /K + /2Cl – cotransporter stoichiometry K + homeostasis The hematophagous hemipteran Rhodnius prolixus ingests blood meals that may exceed 10 times the unfed mass of the insect. Subsequent reduction in the fed insect's mass by rapid elimination of urine in the first...

... glutamate homeostasis in the brain, some of which we list here as a stimulus to further work. First, are there more Na + -dependent glutamate transporters which have not been cloned yet? Second, is the ionic stoichiometry of all the Na + -dependent transporters the same as that of the salamander Müller cell...

... was exchanged with each internal proton during the exchange event. Two additional findings were used to establish the number of external Na + binding sites and the transport stoichiometry of the starfish antiporter. First, amiloride acted as a competitive inhibitor of Na + binding to two external sites...
