Question

What stops the process of diffusion in cells?

Answer 1

Diffusion:

1. Diffusion is a process that occurs as a result of the random mobility of molecules and results in a net movement of matter from a high concentration region to a low concentration zone.
2. Diffusion promotes the passage of molecules into and out of cells.
3. The molecules travel from a higher concentration zone to a lower concentration region until the concentration is equal throughout.
4. The materials being dispersed, as well as the medium in which they are distributed, can be in any of three physical states.
5. Factors affecting diffusion are: Temperature, interaction area, particle size, and steepness of the concentration gradient

Diffusion is stopped by:

1. When the concentration of the material reaches equilibrium, the diffusion process normally comes to an end.
2. In other words, there is no one-way movement.
3. It does not, however, imply that there is no movement at all, only that there is no general movement in one direction.
4. Substance molecules move in both directions equally.
