Mediated transport refers to transport mediated by a membrane transport protein. Substances in the human body may be hydrophobic, electrophilic, contain a positively or negatively charged, or have another property. As such there are times when those substances may not be able to pass over the cell membrane using protein-independent movement. So the cell membrane is imbedded with many membrane transport proteins that allow such molecules to travel in and out of the cell. There are three types of mediated transport: uniport, symport, and antiport. Things that can be transported are nutrients, ions, glucose, etc, all depending on what the cell has need of. Mechanism of transport. A molecule will bind to a transporter protein, altering it's shape. The change of shape or other added substances such as ATP will, in turn, cause the transport protein to alter its shape and release the molecule onto the other side of the cell membrane.

Types of Transport

 * Facilitated diffusion
 * Active transport
