Carrier proteins are membrane proteins that transport a particular substance in the blood or across the cell membrane.
Embedded in the cell membrane these proteins transport substances against the concentration gradient out of or into the cell. Therefore carrier proteins conduct facilitated diffusion and active transport. Each carrier protein is designed to recognize one substance or one group of very similar substances only.

Carrier proteins are protein molecules embedded on the membrane..
By facilitated diffusion, small hydrophilic organic molecules e.g. glucose and amino acid
Example:
The binding of glucose to specific carrier protein causing the carrier protein to alters its shape and releases the glucose into the cell.
NOTE: the movement of molecules follow the concentration gradient... this process doesn't require energy(passive transport)

Facilitated diffusion and lively delivery proteins- enable ingredients to head into and go out the cellular. Structural proteins- enhance the plasma membrane. Receptor proteins- bind with signalling molecules to start a cellular reaction.
