Definition Of Diffusion Concentration Gradient

Diffusion is driven by a gradient in concentration.

Definition of diffusion concentration gradient. Concentration refers to how much of a solute there is compared to solvent a corner of a water tank that has just had salt dumped into it for example would have a much higher concentration of salt than the opposite end of the tank where no salt has reached. Concentration gradient refers to the gradual change in the concentration of solutes in a solution as a function of distance through a solution. The movement of a solute down its concentration gradient is called diffusion gradient a graded change in the magnitude of some physical. Diffusion and concentration gradient simple diffusion is an example of passive transport.

In cell biology a diffusion is a main form of transport for necessary materials such as amino acids within cells 1 the diffusion of solvents such as water through a semipermeable membrane is classified as osmosis. The concept of diffusion is widely used in many fields including physics particle diffusion chemistry biology sociology economics and finance diffusion of people ideas and price. Concentration gradient synonyms concentration gradient pronunciation concentration gradient translation english dictionary definition of concentration gradient. Diffusion is the net movement of anything for example atom ions molecules from a region of higher concentration to a region of lower concentration.

A concentration gradient occurs when a solute is more concentrated in one area than another. Where particles atoms or ions move from an area of higher concentration to lower concentration area by the assistance of a concentration gradient. Concentration gradient definition the gradual difference in concentration of a dissolved substance in a solution between a region of high density and one of lower density. A solution essentially has two major components the solvent the dissolving component e g.
