Active transport. Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentrationâin the direction against some gradient or other obstructing factor (often a concentration gradient).
Active Transport. Facilitated diffusion and active transport are two ways of moving materials across the cell membrane. These two types of transport have many similarities as well as differences. One similarity is in what is transported. In facilitated diffusion, ions, sugars, and salts are transported across the membrane. In active transport, ions, sugars, and salts are also transported.
