Substrate-specific carrier proteins allow rapid transport of polar compounds across membranes. Some carrier proteins facilitate diffusion, transporting compounds down a concentration gradient, whereas others are integrated into an energy-requiring active transport system for the transport of substances against a concentration gradient.
Answer (1 of 5): A carrier protein is a protein which is responsible for transporting specific substances through the cell membrane in which it is fixed and into the cell. Different type of proteins is required to transport different type of substances. Each carrier cell is designed to recognize only one type of substance or a group of similar substances.

The sodium-amino acid carrier system involves the uptake by the cell of a sodium ion and an amino acid by the same carrier protein (cotransporter) on the luminal surface of the intestine. Carrier Proteins Carrier proteins, or transporters, are integral membrane pro- teins that move ions or molecules from one side of the plasma membrane to the other. The carrier proteins have specific binding sites to which ions or molecules attach on one side of the plasma membrane. The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen.

Carrier Proteins. Another type of protein embedded in the plasma membrane is a carrier protein. This protein binds a substance and, in doing so, triggers a change of its own shape, moving the bound molecule from the outside of the cell to its interior; depending on the gradient, the material may move in the opposite direction.

• Channel proteins only pass water soluble molecules, while carrier proteins transport both water soluble and insoluble substances.

Their pioneering work was soon followed by the purification and reconstitution of the phosphate transport protein (PTP, PCP, phosphate carrier) . Extensive searches of the yeast ( S. cerevisiae ) genome made it clear that 35 sequences highly similar to those of the ADP, ATP translocase and the phosphate transporter are present.
