How do the molecules in plasma move

WebDec 11, 2015 · There are several methods for this to happen depending on the type of the molecule and the concentration gradient. The processes that are included are: Diffusion, simple and facilitated. Osmosis. Active uptake. Endo and exocytosis. Simple diffusion happens down concentration gradient for small non polar and uncharged molecules, and … WebMolecules can move through the cell’s cytosol by diffusion, and some molecules also diffuse across the plasma membrane (as shown in the picture above). Each individual substance in a solution or space has its own concentration gradient, independent of the concentration gradients of other materials, and will diffuse according to that gradient.
