Abstract The Na+, K+-transporting adenosine triphosphatase (Na+, K+-ATPase), also often
known as the sodium pump or sodium-potassium pump, is an enzyme, found in nearly all …

This chapter on active transport is intended to be a rather practical treatment of the subject in
terms of what active transport is, how it can be distinguished from other types of membrane …

The intracellular localization of calcium in the saccus vasculosus of the rainbow trout, Salmo
gairdneri Richardson, was studied by means of ultracytochemical and X-ray microanalytical …

In this article, we discuss two changes of the Na+/K+-ATPase protein: in the first, the
phosphorylated enzyme is hydrolyzed and K+ ions bound to the extracellular surface appear …

The central importance of the role of the sodium pump in almost all eukaryotic cells is by
now well appreciated. In cells of the central nervous system the sodium pump is responsible …

The relation of membrane transport of alkali cations to their external concentrations or to
their cellular contents was studied in HeLa cells. Chilling the cells at 0• Ž reversed cell Na+ …

Publisher Summary This chapter presents evidence for the effects of millimolar Mg 2+ on
nucleotide binding and group-specific modifications. The new findings about subunit …

There seems to be no doubt that the Na+/K+-ATPase is the enzyme that represents the
machinery of active transport of sodium and potassium across cell membranes. Very early in …

It is almost 50 years since Harris (1941) and Danowski (1941) showed that glycolysis
energizes net extrusion of Na+ and uptake of K+ in red blood cells, thus providing …

Glutamate transporters play a role in removing extracellular excitatory neurotransmitter, L-
glutamate into the cells. The rate of the uptake depends on the density of the transporters at …
