WebFacilitated diffusion is a type of passive transport that uses specialized proteins, such as channel proteins and carrier proteins, to help molecules move across a cell membrane. In this process, molecules can move down their concentration gradient without requiring any energy input from the cell. WebVisualizing. Fundamentally, the word "gradient" means that in one place, there are a lot of particles, and in another place, there are few particles -- and in between those places, the number of particles changes gradually. Now imagine all these particles moving around. In fact, small particles like atoms are in constant motion and this is what ...

WebThe concept of diffusion is tied to that of mass transfer driven by a concentration gradient, but diffusion can still occur when there is no concentration gradient (but there will be no net flux). History: The concept of diffusion emerged from physical sciences. The paradigmatic examples were heat diffusion, molecular diffusion and Brownian motion.
