Active transport mechanisms 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 must be greater than its concentratio...

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...

In E. coli vesicles, most of these transport systems are coupled to an electrochemical gradient of protons (deltamuH+, interior negative and alkaline) generated primarily by the oxidation of D-lactate or reduced phenazine methosulfate via a membrane-bound respiratory chain. Oxygen or, under ...
Nuclear transport erupts on the slopes of Mount Etna Nuclear pore complexes (NPCs) mediate the active transport of large substrates and allow the passive diffusion of small molecules into the nucleus of eukar... MA Powers,M Dasso - 《Nature Cell Biology》 被引量: 31发表: 2004年 Molecular b...
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...
