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- When molecules move from an area of lower concentration to an area of higher concentration Passive Transport- When molecules move from an area of higher concâ¦entration ot an area of higher concentration (also called diffusion)
