For Active Transport ((hot)) — Definition

: Uses the energy already stored in an electrochemical gradient (created by primary transport) to move a different molecule. It can be a symport (both moving same direction) or antiport (opposite directions).

is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration. definition for active transport

Without active transport, cells would rely solely on equilibrium, which would make complex life impossible. Types of Active Transport : Uses the energy already stored in an

The definition of active transport explains how cells maintain homeostasis. Without it, cells would be slaves to their environment. Active transport allows cells to: cells would rely solely on equilibrium
