Coupled transport example
WebSep 12, 2024 · Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient. Active transport is an energy-driven process where membrane proteins transport molecules across cells, mainly classified as either primary or secondary, based on how energy is coupled to fuel these mechanisms.
