Carrier proteins facilitates the transport of specific substances through intracellular compartments or across the cell membrane. They bond and then drag the molecules across the bilipid layer, releasing them on the opposite side.

∙ 14y agoCarrier proteins are involved in facilitated diffusion and active transport of substances out of or into the cell (e.g. diffusion of sugars, amino acids and nucleosides, uptake of glucose, transportation of salts, glucose, amino acids, etc.). For instance, carrier proteins such as the integral transmembrane proteins embedded in the cell membrane would have a high affinity for specific substances on the cell exterior and would next undergo a conformational change to facilitate the passage of these substances to the cell interior across the membrane barriers.

What is a carrier protein?
A carrier protein is a protein that helps with diffusion of various molecules. Carrier proteins also use ATP to move cell materials.
Glucose and no other sugar is transported into cells by protein carrier molecules in the cell surface membrane. How do carrier molecules specifically recognize glucose?
the receptors on the protein carrier recognise glucose allowing it to enter the cell :)
Primary active transport involves a conformational change in the carrier protein The most immediate stimulus for this is?
phosphorylation (binding of the carrier protein to a phosphate group) within the cell
What is the best carrier protein pump in animal cells?
Animal cells' best-known carrier pump is their stomach.
What are responsible for the transport of substances down a concentration gradient during facilitated diffusion?
Carrier proteins.
What is a carrier protein?
A carrier protein is a protein that helps with diffusion of various molecules. Carrier proteins also use ATP to move cell materials.
Is the sodium potassium pump a carrier protein?
the carrier protein of Na-k pump is an ion carrier protein and the pump cannot be termed as the carrier protein its a biochemical phenomenon
What is a protein used to transport specific substances?
carrier protein
How does facilitated diffusion work?
It is a passive process utilizing a protein carrier or channel.
The passive form of a carrier protein is called?
Protein channels.
How does a protein transport substances across a cell membrane?
carrier protein
What protein helps things across a cell membrane?
Carrier Protein
Are both zinc and iron transported in the blood by a fat carrier?
No. Its by a protein carrier.
What changes occur to a carrier protein once it binds to its target molecules?
the carrier protein changes shape to release the molecule inside of a cell
Is sodium a protein?
I think Sodium is protein because I forget what is a protein and a sodium
Through what type of proteins does active transport occur?
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
Glucose and no other sugar is transported into cells by protein carrier molecules in the cell surface membrane. How do carrier molecules specifically recognize glucose?
the receptors on the protein carrier recognise glucose allowing it to enter the cell :)
