However, in the past couple of decades, many carrier proteins (transporters ... (but not all) cell types, at least in intestinal membrane permeation. Carrier-mediated transport is probably ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...
