- Simple diffusion and passive transport (article) | Khan AcademyIn cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we’ll look in more detail at membrane permeability and different modes of passive transport.
- 9: Diffusion - Chemistry LibreTextsDiffusion can be described as the random movement of particles through space, usually due to a concentration gradient. Diffusion is a spontaneous process and is a result of the random thermal motions between two particles. The diffusion coefficient (\(D\)) can be solved for with Fick’s laws of diffusion, which are broken up into two laws.
- Diffusion | Definition & Examples | Britannicadiffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
- Diffusion - Definition, Examples and Types | Biology DictionaryDiffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states.
