WebAug 26, 2024 · Concentration Gradient Definition Biology. In cell biology, diffusion is a main form of transport for necessary materials such as amino acids within cells.[1] The diffusion of solvents, such as water, through a semipermeable membrane, is classified as … WebFacilitated diffusion can be distinguished from a purely diffusional mechanism because facilitated diffusion is saturable and it is specific. Plots of the flux versus the concentration are not linear, as you would expect from the diffusion mechanisms as shown in Eqns [2.5.8] and [2.5.13]. The rate increases with concentration but only up to a ...
