What are the three characteristics of carrier mediated transport?
What are the three characteristics of carrier mediated transport?
Carrier-mediated transport exhibits the properties of specificity, competition, and saturation.
Which of the following is the characteristic of carrier?
The correct answer is (b) it exhibits a specificity for a particular type of molecule. Carrier proteins move molecules across the cell membrane.
What are the characteristics of carrier proteins?
A carrier protein is a transport protein that is specific for an ion, molecule, or group of substances. Carrier proteins “carry” the ion or molecule across the membrane by changing shape after the binding of the ion or molecule. Carrier proteins are involved in passive and active transport.
What are carrier mediated transport mechanisms?
Carrier-mediated transport is an energy-dependent pathway generally used by small hydrophilic molecules. There are specific receptors on the membrane of carriers that recognize the target molecules and transport them across the cell.

Which of the following is characterized by carrier mediated transport down a chemical concentration gradient?
Answer and Explanation: The answer is b) Facilitated Diffusion. Facilitated diffusion, which is also known as passive-mediated transport, is a mode of transport across the…
What is specificity in carrier-mediated transport?
Carrier-mediated transport. When integral proteins bind specific ions or organic substrates and carry them across the plasma membrane. Characteristics of carrier-mediated transport. 1. Specificity – Each carrier protein will bind and transport only specific substances.
Which of the following is a characteristic feature of a carrier protein in a plasma membrane *?
Which of the following statements describes a characteristic feature of a carrier protein in a plasma membrane? It exhibits specificity for a particular type of molecule.
What is the one great advantage of carrier mediated active transport?
What is the one great advantage of carrier-mediated active transport? It is not dependent on a concentration gradient.
What are the functions of carrier proteins in active transport?
Carrier proteins bind specific solutes and transfer them across the lipid bilayer by undergoing conformational changes that expose the solute-binding site sequentially on one side of the membrane and then on the other.
What is carrier mediated transport also called?
It is also known as type 2 facilitated transport or carrier-facilitated transport (Ho and Li 1992). A carrier reagent is incorporated in the membrane phase to transfer the diffusing specie from the feed phase to the product phase across the membrane phase.
