What factor determines the direction of diffusion?
The concentration gradient for that substance determines the direction of net movement of molecules in passive transport.For example:When the concentration is high or that substance, it would move from the higher concentration to a lower concentration. And vice versa.
What term defines the movement of material along a concentration gradient through protein channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
What term defines the movement of materials along the concentration gradient through protein channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
How can diffusion occur in one direction?
Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.Explanation:Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
Why osmosis is a type of diffusion?
Because it is the movement of molecules from areas of high concentration to areas of low concentration in the direction of the concentration gradient. Osmois specifically implies the diffusion of water.
How long does movement occur across a concentration gradient?
As long as there is a concentration gradient. This is because diffusion occurs which is the net movement of substances from a region of high concentration to a region of low concentration.
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration

What concentration gradient moves when a low concentration moves from an area of a higher concentration?
The concentration gradient is controlled by Diffusion. This same movement in reverse is known as Osmosis.
A concentration gradient ceases to exist when?
There is no net movement.
What defines the movement of material along a concentration gradient through a protein channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
What term defines the movement through a concentration gradient through protein channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.

Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
What term defines the movement of materials along concentration gradient through channels?

Is the movement of a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is the movement a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
