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
What else can I help you with?
What is the overall goal of diffusion osmosis and facilitated diffusion?
The overall goal of diffusion, osmosis, and facilitated diffusion is to achieve equilibrium by moving substances across cell membranes. Diffusion involves the passive movement of molecules from an area of higher concentration to lower concentration. Osmosis specifically refers to the movement of water across a semi-permeable membrane to balance solute concentrations. Facilitated diffusion uses specific transport proteins to help molecules that cannot easily cross the membrane to move down their concentration gradient.
In which direction do channels using facilitated diffusion work?
Left
Why isnt cellular energy required for the passenger molecule to be carried across the cell membrane by the carrier molecule?
Because of facilitated diffusion(, which nutralizes it from a higher to a lower concentration.)
How do particles move from an area of high to an area of low concentration?
In cells, diffusion moves by facilitated diffusion, active transport, ABC transporters, group translocation or osmosis. Some of these move molecules from a low concentration to a higher and against the gradient.Simple diffusion moves molecules from a high concentration to a lower concentration.
What is the natural tendency of molecules to spread evenly through a room?
Diffusion
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What is the difference between diffusion and facilitate diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
What is the use of carrier proteins for diffusion?
facilitated diffusion.
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
Diffusion requires what?
Facilitated diffusion requires membrane proteins
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
How much ATP does the Facilitated diffusion cost the cell?
Facilitated diffusion is an inactive mode.So no ATP cost.
What are some examples of passive transport?
diffusion facilitated diffusion osmosis
What are three parts of passive transport?
diffusion, facilitated diffusion, and osmosis
