WebVideo transcript. - In the first video where we introduced the idea of diffusion and concentration gradients, we had a container with only one type of particle in it, we had these purple particles. And in our starting scenario we had a higher concentration of the purple particles on the left-hand side than we had on the right-hand side. WebMar 5, 2024 · Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.

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 ...
