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.

What is the function of the carrier protein?

The function of a carrier protein is to carry substances across the membrane of a cell.


What is a solute molecule referred to when it passes through the membrane passively using a carrier protein?

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.

What do carrier proteins do in facilitated diffusion?

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.


What are the two types of membrane transport protein?

The two types of membrane transport proteins include protein channels and carrier proteins.

How do carrier protiens transport substances across cell membrane?

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?

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.


Does active transport require a membrane protein?

Active transport does require a carrier protein. Each protein is specific to one particular molecule.


Does osmosis require a carrier protein and energy?

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.
