Carrier proteins are globular proteins which are specific in their actions, and thus regulate the entry and exit of particles into the cell. They help in the conduction of ionic substances and polar substances.
It exhibits a specificity for a particular type of molecule.
The function of a carrier protein is to carry substances across the membrane of a cell.
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
The type of membrane transport across a membrane that requires a carrier protein is active transport. This is also known as facilitated diffusion.
A carrier protein
active membrane transport
The carrier protein changes shape , shielding the molecule from the interior of the membrane.
A carrier protein is located in the membrane of a cell. It works by actively transporting substances against the concentration gradient.

facilitated diffusion is also called cell-mediated diffusion because a substance transport in this manner diffuses through the membrane using a specific carrier protein to help.first, carrier protein binds to the binding site of the carrier protein ,and then there is a conformational change in the shape of the carrier protein that helps the molecule to diffuse other side of the membrane.
The two types of membrane transport proteins include protein channels and carrier proteins.
* nobody knows how that happens
1-A carrier prrotein binds to a molecule on one side of the cell membrane. 2-The carrier protein changes shape,shielding the molecule from the interior membrane. 3-The molecule is released on the other side of the membrane.
Facilitated diffusion carrier protein and cell-membrane pumps both are specific for the things that they transport. Facilitated diffusion is an example of passive transport.
Active transport does require a carrier protein. Each protein is specific to one particular molecule.
No, it's passive transport - that means it doesn't require energy to diffuse. Osmosis is the diffusion of water through a semi-permeable membrane, so no carrier protein is needed for it to pass through the membrane.
the receptors on the protein carrier recognise glucose allowing it to enter the cell :)
carrier protein take some molecules with themselves which are required for cell
