How does Facilitated diffusion differs from diffusion in that facilitated diffusion?
Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.
What is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
The mixing and spreading of particles in gases and liquids is called diffusion?
Yes. Diffusion is the movement of particles from where they are in high concentration to where they are in low concentration.
Does facilitated diffusion require the Cell to use energy?
No, there is no ATP used in facilitated diffusion, because it is a form of passive transport. It only differs from normal diffusion in that it uses transport proteins to move larger or more polar molecules across the membrane of the cell.
When substances pass through diffusion they move from areas of their what to areas of their what?
it moves from high to low concentration
Are responsible for the transport of substances down a concentration gradient during facilitated diffusion.?
Carrier proteins
What happens in the process of facilitated diffusion In what part of the membrane does it take place?
In facilitated diffusion, substances will still diffuse down their concentration gradient but they make use of a transport protein.
What are some characteristics of facilitated diffusion?
The substances are moving from areas of high concentration to areas of low concentration with the help of a protein channel.
Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
How is facilitated diffusion different than normal diffusion?
Diffusion is the movement of molecules or partocles from an area of high concentration to an area of lower concentration, and Facilitated diffusion is when substances difuse across cell membranes more rapidly than you might expect.
Facilitated diffusion sentence?
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
Facilitated diffusion carrier proteins and cell membrane pumps both?
They both transport substances up their concentration gradients.
What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins
What are responsible for the transport of substances down a concentration gradient during facilitated diffusion?
Carrier proteins.
A form of passive transport that involves membrane proteins to aid in the movement of substances?
Facilitated diffusion
Facilitated diffusion and active transport?
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
What particle movement from an area of higher concentration to an area of lower concentration?
they move from an area of high concentration to low concentration in an effort to create equilibrium.
