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. Active transport is the process of using energy to move materials through a membrane. This process is different from diffusion and other types of passive transport, which do not require energy.ctive Transport.
