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.
it moves large molecules or molecules that are not soluble in lipids across across the cell membrane. (Pg. 101 in science book...1st para.)
Proteins play a key role in aiding diffusion across cell membranes by acting as channels or carriers. Cell recognition is facilitated by cell surface markers such as glycoproteins and glycolipids, which help cells identify and communicate with each other.
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
In animal cells, substances are transported primarily through the plasma membrane via processes like diffusion, facilitated diffusion, and active transport. Additionally, intracellular transport occurs through organelles such as the endoplasmic reticulum and Golgi apparatus, which help in the synthesis and movement of proteins and lipids. Vesicles also play a crucial role in transporting materials within the cell and to the cell membrane for secretion.
The structure that regulates what enters and leaves a cell is the cell membrane, also known as the plasma membrane. It is primarily composed of a phospholipid bilayer with embedded proteins that facilitate transport. This selective permeability allows the membrane to control the movement of substances, maintaining the internal environment of the cell. Additionally, various transport mechanisms, such as passive diffusion, facilitated diffusion, and active transport, play crucial roles in this regulation.
Proteins play a role in facilitated diffusion by acting as channels or carriers that help specific molecules pass through the cell membrane. These proteins facilitate the movement of molecules that are too large or polar to pass through the membrane on their own.

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
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.

A carrier protein is a type of protein that helps transport specific molecules across cell membranes. These proteins bind to molecules on one side of the membrane and release them on the other side, facilitating their movement into or out of cells. Carrier proteins play a crucial role in maintaining cellular function by regulating the transport of essential molecules.

Transport proteins play a critical role in facilitating the movement of molecules across biological membranes, such as ions, nutrients, and waste products. They help maintain cellular homeostasis by regulating the flow of substances into and out of the cell. Transport proteins can be passive (facilitated diffusion) or active (requiring energy).
