Why would facilitated diffusion picture?
Facilitated diffusion is used when molecules are too large or polar to pass through the cell membrane on their own. It involves the help of carrier proteins that aid in transporting specific molecules across the membrane down their concentration gradient. This process does not require energy input from the cell.
When would facilitated diffusion be used?
Facilitated diffusion is used when molecules need to move across a cell membrane from an area of high concentration to an area of low concentration, but cannot pass through the lipid bilayer on their own. In facilitated diffusion, carrier proteins or channel proteins help facilitate the movement of these molecules across the membrane.
Facilitated diffusion moves large molecules through what?
Glucose and polypeptides.
How would you define diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
Is Diffusion made of small or large molecules?
Diffusion is not a substance. It is a physical process. Diffusion is the process where there is a movement of molecules from where they are abundant to where they are scarce. A more technical definition would be: Diffusion is a process in which molecules move from a region of higher concentration to a region of lower concentration.
How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
Which describes one of the ways proteins behave in facilitated diffuson?
In facilitated diffusion, proteins act as transporters or channels that help specific molecules cross the cell membrane more efficiently than they would by simple diffusion. These proteins undergo conformational changes to facilitate the movement of substances, such as glucose or ions, down their concentration gradient. This process does not require energy, as it relies on the natural kinetic energy of the molecules. Thus, facilitated diffusion enhances the selectivity and speed of transport across the membrane.
Why would the body use facilitated diffusion to move the amino acids instead of diffusion?
Facilitated diffusion is used for amino acids because they are polar molecules and cannot diffuse through the cell membrane on their own. Facilitated diffusion relies on carrier proteins to transport amino acids across the membrane, helping them move from an area of high concentration to low concentration. This process is quicker and more efficient than simple diffusion for polar molecules.
How would you define cellular diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
What is the difference between simple diffusion and facilitated diffusion?
It doesn't. (answer by RRU member Cyrem)
Is diffusion better in a solid or a gas?
What kind of diffusion? If it is diffusion of molecules then gas would be the right platform
Which process would be describe the movement of sugar molecules through membrane from a region of higher concentration to a region of lower concentration?
This process is called passive transport or facilitated diffusion, where sugar molecules move down their concentration gradient without requiring energy input from the cell. Proteins in the membrane facilitate the movement of sugar molecules across the membrane.
