Is simple diffusion selective
Witryna5 kwi 2024 · Simple diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration. Facilitated diffusion, on the other hand, is the passive movement of molecules across a cell membrane with the aid of a specific transport protein. ... Unlike simple diffusion, facilitated diffusion is selective … Witryna13 lip 2024 · Simple diffusion through protein channels. The diffusion of water and water-soluble substances occurs through channel proteins. The channels are highly selective. Thus, the sodium channel is specifically selected for the passage of sodium ions, Conversely, another set of protein channels is selective for potassium transport.
