Re: What is Active Transport ?
Active Transport
Active transport is the pumping of molecules or ions through a membrane against their concentration gradient. It requires:
* a transmembrane protein (usually a complex of them) called a transporter and
* energy. The source of this energy is ATP.
The energy of ATP may be used directly or indirectly.
* Direct Active Transport. Some transporters bind ATP directly and use the energy of its hydrolysis to drive active transport.
* Indirect Active Transport. Other transporters use the energy already stored in the gradient of a directly-pumped ion. Direct active transport of the ion establishes a concentration gradient. When this is relieved by facilitated diffusion, the energy released can be harnessed to the pumping of some other ion or molecule.
Now I know what is Active transport
