Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
What is true statements about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
What is A true statement about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
What influences the rate of diffusion?
The rate of diffusion increases with temperature. The rate of diffusion also increases with the concentration gradient and the surface area.
What is an example of diffusion in a sentence?
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
What controls the rate of diffusion?
The rate of diffusion is directly related to the concentration of gradient. For example, the greater the amount between the concentration of the areas, the greater the greater to difference in diffusion.
What three things can affect the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
What factors affect the diffusion rate?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
What is diffusion rate proportional to?
rate of diffusion depends on the concentration gradient, surface area, distance over which diffusion takes place, size and nature of the diffusing molecule.
What factor affects the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
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.
Why is facilitated diffusion faster than simple diffusion?
Facillatated diffusion is faster than simple diffusion when solute concentration is low because it uses channels to transport molecules throught the lipid bilayer. Simple diffusion depends upon concentration gradients so the net movement of diffusing molecules depends on the concentration gradient, thus the rate of diffusion is directly proportional to the concentration gradient. Simple diffusion is also a type of passive transport, which requires no energy input, whereas facilitated diffusion is protein mediated transport. Passive diffusion of solute into a cell is linearly related to the concentration of solute outside the cell. Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell. Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute.
