- Diffusion - Wikipedia
Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration Diffusion is driven by a gradient in Gibbs free energy or chemical potential It is possible to diffuse "uphill" from a region of lower concentration to a region of higher concentration, as in spinodal decomposition
- Diffusion - Definition, Examples and Types | Biology Dictionary
Diffusion 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
- Diffusion | Definition Examples | Britannica
Diffusion, 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 - BYJUS
Diffusion is widely used in various fields such as biology, physics, chemistry, etc Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion Simple diffusion A process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins For example, bacteria deliver small nutrients, water and oxygen into

- Diffusion – Definition, Causes, Significance, Examples
1 Simple Diffusion Definition: Simple diffusion involves the direct movement of molecules across a semi-permeable membrane without the help of transport proteins Conditions: The solute should be non-polar and have a low molecular weight (under 10,000 kDa) Examples: Movement of gases like oxygen and carbon dioxide in and out of cells Transport of water molecules and nutrients in bacteria
- Diffusion - Simple - Facilitated - TeachMePhysiology
Types of Diffusion Diffusion across the cell membrane is either simple or facilitated An example of a membrane transport protein involved in facilitated diffusion is the GLUT-2 protein, which is the primary protein involved in the transfer of glucose from the liver into the blood
- Diffusion - Definition, Examples, Types, Factors effecting Causes
Diffusion – Definition, Examples, Types, Factors effecting Causes Diffusion is the natural movement of particles from an area of high concentration to one of low concentration, driven by differences in concentration or energy levels This principle is universal, applying not only to physical and chemical processes but also to the spread of ideas, data, and financial trends Remarkably
