Cell membranes: diffusion and osmosis part 1: diffusion diffusion is a process by which molecules move into or out of cells to diffuse into or out of a cell, molecules must pass through the cell membrane. The recently introduced method of excess collisions (mec) is modified to estimate diffusion-controlled reaction times inside systems of arbitrary size the. Biological functions of dna depend on the sequence-specific binding of dna-binding proteins to their corresponding binding sites binding of these proteins to their binding sites occurs through a facilitated diffusion process that combines three-dimensional diffusion in the cytoplasm with one.
