Equilibrium state of ATP-driven ion pumps in relation to physiological ion concentration gradients
Dear Sir: The purpose of this communication is to show that the Ca ion concentration gradient across the sarcoplasmic reticulum membrane of a resting skeletal muscle cell is close to what would be predicted for the equilibrium state of the ATP-driven Ca pump. The Na and K gradients across the plasma membranes of erythrocytes or of a resting squid axon, however, fall far short of the predicted e...
متن کاملThe Equilibrium between Hemolytic Sensitizer and Red Blood Cells in Relation to the Hydrogen Ion Concentration
1. In a salt-free medium the proportion of the total amount of hemolytic sensitizer present, combined with the homologous cells, reaches a maximum of almost 100 per cent at pH 5.3. On the alkaline side of this point the proportion combined diminishes with the alkalinity and reaches a minimum of approximately 5 per cent at pH 10. On the acid side of pH 5.3 the proportion combined diminishes with...

متن کاملSputter-ion Pumps
The following paper outlines the working principles of sputter-ion pumps. The pumping mechanisms for reactive and inert gas species, as well as argon instability are explained. The operating pressure range, special designs for integrated linear pumps in accelerators and operational aspects are discussed.
متن کاملRelation of amino acid transport to sodium-ion concentration.
The dependence of amino acid transport on the presence and the distribution of the alkali metals was first noted in I9521. In 1958 RIGGS, WALKER AND CHRISTENSEN showed that the ability of the Ehrlich cell to accumulate glycine decreased in proportion to the extent that Na + replaces cellular K + (ref. 2). The results of that research (Fig. 6 in ref. 2) effectively dissociated the ability of the...
