What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Is diffusion an active mechanism?
False
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
The larger the concentration gradient (bigger difference between the two solutes across semipermeable membrane) the faster the rate of diffusion.
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.
What is the purpose or goal of diffusion?
The ultimate goal is to produce Proteins and Carbohydrates for the cell and their organelles.
Movement of a substance down the substance's concentration gradient?
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.
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.

False
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
The larger the concentration gradient (bigger difference between the two solutes across semipermeable membrane) the faster the rate of diffusion.
Diffusion continues until there is no?
Concentration gradient. After there's no concentration gradient, equilibrium occurs, which means no more diffusion.
What is diffusion in science terms?
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
COMPARE osmosis and diffusion?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
Diffusion in the states of matter?
Diffusion is the movement of particles from an area of high concentration to an area of a lower concentration down a concentration gradient.
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.
Diffusion is the process of movement of molecules under a concentration gradient?
Yes
