WebActive transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. WebActive transport is the movement of molecules against their concentration gradient, using specialised carrier proteins and energy in the form of adenosine triphosphate (). This ATP is generated from cellular metabolism and is needed to change the conformational shape of the carrier proteins.. This type of transport is different from the passive forms of …

WebBecause this type of active transport is not powered directly by the energy released in cell metabolism ( see below Primary active transport ), it is called secondary. There are two kinds of secondary active transport: counter-transport, in which the two substrates cross the membrane in opposite directions, and cotransport, in which they cross ... WebActive transport. During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the …
