What Active Transport 👑
Active transport is a vital, energy-driven process that allows cells to control their internal environment with precision. While passive transport handles equilibrium-based needs, active transport creates the disequilibrium —the differences in concentration and charge—that makes life processes like thinking, moving, and growing possible. Without it, cells would be at the mercy of their surroundings and could not maintain the order necessary for life.
Transporters are categorized by the direction and number of molecules they move: Moves one specific molecule in one direction. what active transport
