Active transport relies on specialized proteins embedded in the cell membrane that act as "pumps". There are two primary categories based on how they use energy: what active transport

is the movement of molecules or ions across a cell membrane against their concentration gradient (from an area of low concentration to an area of high concentration). Because this movement opposes the natural tendency of diffusion, it requires an input of chemical energy . Longdom Publishing SL Active transport: primary & secondary

Active transport is a vital biological process where cells move molecules or ions —from an area of lower concentration to an area of higher concentration . Because this movement is "uphill," it requires an input of metabolic energy, typically in the form of Adenosine Triphosphate (ATP) . Core Mechanisms and Types

Active transport is a type of cellular transport that involves the movement of molecules across the cell membrane from an area of lower concentration to an area of higher concentration, against the concentration gradient. This process requires energy, usually in the form of ATP (adenosine triphosphate), to pump molecules against their natural direction of movement.

Moves two different molecules in the same direction simultaneously.
