The transport of cell cargo, such as organelles and protein complexes in the cytoplasm, is determined by cooperative action of molecular motors stepping along polar cytoskeletal elements. Analysis of transport of individual organelles generated useful information about the properties of the motor proteins...
active transport n. The movement of a chemical substance through a gradient of concentration or electrical potential in the direction opposite to normal diffusion, requiring the expenditure of energy:active transport across a cell membrane. American Heritage® Dictionary of the English Language, Fifth...
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...
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 ...

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 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...
