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.

∙ 11y agoit helps it because the molecule that is trying to pass by is not small enough to go through the lipid bilayer. The protein carriers is like a tube that helps the molecule get form one side to another without using energy.

What role do carrier protein play in facilitated diffusion?
it moves large molecules or molecules that are not soluble in lipids across across the cell membrane. (Pg. 101 in science book...1st para.)
What role do active and passive transport play in absorption?
Sodium ions are actively transported out of the epithelial cells by the sodium-potassium pump into the blood, this takes place in one type protein-carrier molecule There is now a much higher concentration of sodium ions in the lumen than inside of the epithelium cells The sodium ions diffuse into the epithelial cells through a different type of protein carrier, as the sodium ions flood back in through this second carrier protein they couple with te glucose molecules which are carried into the cell with them The glucose passes into the blood plasma by facilitated diffusion using another type of carrier
What role does diffusion play in cellular respiration?
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
What roles will diffusion and effusion play in transporting the gas from inside the balloon throughtout the room?
No
What role does nitrogen play in plant synthesis?
well i ma doing test corrections on that question now, so i can tell you that it is either proteins, gluclose, or waxes, but i think its either protiens or waxes. :)
What occurs when substances move against the concentration gradient requires and the aid of carrier proteins?
Carrier molecules are molecules that play a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.

Diffusion and facilitated diffusion?
Diffusion:Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. The time dependence of the statistical distribution in space is given by the diffusion equation. The concept of diffusion is tied to that of mass transfer driven by a concentration gradient, but diffusion can still occur when there is no concentration gradient (but there will be no net flux). diffusion is invoked in the social sciences to describe the spread of ideas.Facilitated diffusion:Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism

How does size play a role in diffusion?
no answer.
What role does proteins play in living things?
Protiens code DNA and RNA. They also act as building blocks for the body
What role does diffusion play?
it plays the cool side
What NFL team does Derek Carrier play for?
Derek Carrier plays for the San Francisco 49ers.
What role does diffusion play in cellular respiration?

What position does Derek Carrier play?
Derek Carrier plays Tight End for the San Francisco 49ers.
What college did NFL player Derek Carrier play for?
NFL player Derek Carrier played for Beloit.
What role does active transport play in diffusion?
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
