How do proteins play a role in facilitated diffusion?
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.
What role do carrier protiens play 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 is a carrier protein?
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.

Difference between receptor proteins and carrier proteins?
Receptor proteins are specialized proteins that bind specific molecules, such as hormones or neurotransmitters, triggering a cellular response. Carrier proteins, on the other hand, are involved in transport processes, helping to move molecules across cellular membranes. While receptor proteins facilitate communication and signaling within the cell, carrier proteins play a more functional role in transporting molecules.
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.

What role do carrier proteins play in the process of active transport?
Carrier proteins play a crucial role in active transport by helping move molecules across the cell membrane against their concentration gradient. These proteins bind to specific molecules and change shape to transport them across the membrane, requiring energy in the form of ATP.
What organelle similar to diffusion?
The organelle similar to diffusion is the cell membrane, which regulates the movement of substances in and out of the cell. It allows small molecules and ions to pass through via simple diffusion, balancing concentrations inside and outside the cell. Additionally, the membrane contains proteins that facilitate facilitated diffusion, helping larger or polar molecules cross more efficiently. Thus, the cell membrane plays a crucial role in maintaining homeostasis through diffusion-like processes.
Describe the role of carrier proteins during active transport?
they work as a catalysator for the transportation. They lower the nessesary energy for a transport to start. This can in many cases only be achieved by highly specifically adapted carriers, which in cells is mostly proteins.
What is the name of the proteins that aid ions and large insoluble particles across the cell membrane?
The proteins that aid ions and large insoluble particles across the cell membrane are called transport proteins. These include channel proteins, which allow specific ions to pass through, and carrier proteins, which facilitate the transport of larger molecules by changing shape. Together, they play a crucial role in maintaining cellular homeostasis by regulating the movement of substances in and out of the cell.
How do transport proteins move substances across membranes?
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.*This is from Wikipedia.....
