a gradual change in the concentration of solutes in a solution as a function of distance through a solution. 2. the gradual difference in the concentration of solutes in a solution between two regions. In Biology, a gradient results from an unequal distribution of ions across the cell membrane. When this happens, solutes move along a concentration gradient. This kind of movement is called diffusion.
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.
Yes, diffusion is quicker when there is a higher concentration gradient because it drives the movement of molecules from areas of higher concentration to areas of lower concentration more rapidly. The steeper the concentration gradient, the faster the rate of diffusion.
Facilitated diffusion moves molecules with the concentration gradient, from an area of high concentration to an area of low concentration.
In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
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.
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.
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
a gradient
Yes it does.
diffusion is occur when different concentration gradient is applied
Diffusion continues until there is no longer a concentration gradient present between the two regions. Once equilibrium is reached, the molecules will be evenly distributed throughout the system and diffusion will stop.
The greater the concentration gradient, the faster the rate of diffusion.
The greater the concentration gradient, the faster the rate of diffusion.
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
Simple diffusion
Yes, diffusion is quicker when there is a higher concentration gradient because it drives the movement of molecules from areas of higher concentration to areas of lower concentration more rapidly. The steeper the concentration gradient, the faster the rate of diffusion.
Facilitated diffusion moves molecules with the concentration gradient, from an area of high concentration to an area of low concentration.
