Glucagon stimulation of mitochondrial ATPase and potassium ion transport.
The hormone glucagon stimulates hepatic gluconeogenesis. Studies on the mechanism of this stimulation have centered upon those changes manifested in the hepatic mitochondria after the hormonal treatment [l-5] . Recently, acute glucagon treatment of fed, intact rats has been shown to produce a stimulation of respiration with a number of substrates in isolated, hepatic mitochondria [5]. Rates of ...
متن کاملNMR studies identify four intermediate states of ATPase and the ion transport cycle of sarcoplasmic reticulum Ca2+-ATPase.
Water proton nuclear relaxation measurements are used to detect and characterize four distinct intermediate states for Gd3+ bound to Ca2+ sites of sarcoplasmic reticulum Ca2+-ATPase in complexes with ATP analogues. In the absence of nucleotides, Gd3+ binds to two occluded Ca2+ transport sites on Ca2+-ATPase which have a low accessibility to solvent water. In the presence of the nonhydrolyzable ...
متن کاملINSECT MALPIGHIAN TUBULES: V-ATPase ACTION IN ION AND FLUID TRANSPORT.
Insect Malpighian tubules secrete fluid into the lumen as part of their function as excretory organs. The underlying ion transport is, when stimulated, faster than in any other known tissue. It is driven by the activity of an H+-transporting V-ATPase situated on the luminal cell membranes. This ATPase, together with cation/H+ antiporter(s), constitutes a common cation pump which can transport s...
متن کاملHybrid Molten/Solid In2O3-Bi2O3 Oxygen Ion Transport Membranes
The hybrid molten/solid In2O3 - 30-48 wt.% Bi2O3 oxide materials were studied with respect to their transport properties. The conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe DC, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. We show that the...
