Why are gradients important in diffusion and osmosis

WebApr 8, 2024 · Both of these processes, diffusion and osmosis tend to equalize the concentration of the solution. Both of these processes do not require any extra energy or input hence these are called passive processes. Both of these processes observe the movement of molecules from higher concentration areas to lower concentration areas. Webdiffusion. Diffusion is the movement of a substance (e.g. molecules and ions) from a region of higher concentration to one of lower concentration. Diffusion is a passive process, meaning that it occurs without the expenditure of energy. The energy driving diffusion comes only from the intrinsic kinetic energy found in all atoms, ions, and ...
