Passive transport in the largest biology dictionary online. Free learning resources for students covering all major areas of biology.
Active:An Active transport in biology refers to the process by which molecules or ions are actively transported across a cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. Passive:An Passive transport, also known as passive dif...
Passive transport of Ca2+ ions through lipid bilayers imaged by widefield second harmonic microscopy In biology, release of Ca 2+ ions in the cytosol is essential to trigger or control many cell functions. Calcium signalling acutely depends on lipid membra... M Eremchev,D Roesel,CS Poojari,....
Kristin has taught college Biology courses and has her doctorate in Biology. In this lesson, we've learned several different methods of passive transport, or transport across the cell membrane that does not require energy. Passive transport moves across a concentration gradient, or a gradual differe...
Passive transport occurs in the direction expected for the existing driving force, which in the case of ions involves the chemical gradient (given by the difference in concentration between the two sides of the membrane) and the electrical gradient (given by the transmembrane electrical potential ...

Step 2: Definition of Active Transport- Active transport, on the other hand, is the movement of molecules against their concentration gradient, from areas of lower concentration to areas of higher concentration. This process requires energy, typically in the form of ATP (adenosine triphosphate). St...
