Hello Ariana! Molecular weight and diffusion are inversely proportional; the greater the molecular weight, the slower the rate of diffusion. In fact, certain molecules can never pass through membranes, thus protecting the cell. I am not sure I understand your theory and second question.
Difference Between Simple Diffusion and Facilitated Diffusion. Simple Diffusion vs Facilitated Diffusion. In cell biology, diffusion refers to passive transport and it is the net movement of particles from an area of high concentration to an area of low concentration. When molecules are evenly spread across a cell, it is called equilibrium.
