Three types of diffusion are distinguished, viz., molecular, Brownian, and turbulent.
WebThere are two major methods for moving molecules across a membrane, and it is related to whether or not cell energy is used. Passive mechanisms, such as diffusion, require no energy to function, whereas active transport does. In passive transport, an ion or molecule crosses the membrane and moves down its concentration or electrochemical gradient. Web3. Diffusivity measures speed of movement- it is one half of the mean square displacement of a number of molecules per unit time through a given medium. 4. Diffusivity for gases are the highest due to their highest mobility. They are lower for liquids and the lowest for solids. 5. Diffusivity of a gas in porous solid depends on the porous ...
