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 ...

WebRole of Electrochemical Gradient in Biological Process. Electrochemical gradient determines the direction of movement of substances in biological processes by diffusion and active transport. The diffusion and active transport generate an electrochemical potential across the membrane. Each model of diffusion expresses the diffusion flux with the use of concentrations, densities and their derivatives. Flux is a vector representing the quantity and direction of transfer. Given a small area with normal , the transfer of a physical quantity through the area per time is where is the inner product and is the little-o notation. If we use the notation of vector area then The dimension of the diffusion flux is [flux] = [quantity]/([time]·[area]). The diffusing physical quan…
