Other articles where active transport is discussed: biophysics: Biological membranes: Ussing’s definition of active transport made possible an understanding, at the cellular level, of the way in which ions and water are pumped into and out of living cel
ion transportU937 cellsLithium transport across the cell membrane is interesting in the light of general cell physiology and because of its alteration during numerous human diseases. The mechanism of Li~+ transfer has been studied mainly in erythrocytes with a slow kineticsof ion exchange and ...
Intact cell membranes were required. Glucose concentration in the medium, attempts to manipulate the intracellular electrolyte composition by means of leaching and variations of external calcium, magnesium and phosphate had no effect on this system. Two-thirds of the transport of AIB into bone cells ...
Active Transport of Na+ and K+ through Animal Cell Membranes The transport of Na+ out of the cell and K+ into the cell against a concentration gradient is catalyzed by a (Na+ + K+)-activated ATPase. The way in which ... PDW Schoner - 《Angewandte Chemie International Edition in Engl...
In bacteria, the driving force of the active transport comes from ATPhydrolysisor more commonly from the electrochemical H+gradient (ΔμH+) across the membrane, called theproton motive force. The proton concentration outside the cell (+) is higher than inside (−) the cell, and there is...
ON THE MECHANISM OF TAURINE TRANSPORT AT BRAIN CELL MEMBRANES One non-saturable and two saturable transport systems were demonstrated for taurine in rat brain slices. One of the saturable systems, designated β, is ch... P.,L,src=http://onlinelibrarystatic.wiley.com/undisplayable_characters/000...
Active Transport vs. Passive Transport Passive transport is another form of cellular transport. It is one of the mechanisms employed by a cell to move substances across a biological membrane. It differs from active transport in the way that the substances move not against but along the direction...
Active transportmechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient—that is, if the concentration of the substance inside the cell is greater than its concentration in ...
