What are the similarities between active transport and diffusion?

WebbFacilitated diffusion is the passive movement of molecules across the cell membrane via the aid of a membrane protein. It is utilised by molecules that are unable to freely cross the phospholipid bilayer (e.g. large, polar molecules and ions) This process is mediated by two distinct types of transport proteins – channel proteins and carrier ... WebbHowever, active transport requires energy as the substances involved move against the concentration gradient, from low to high concentration. This energy is derived from ATP (adenosine triphosphate), energy-rich molecules in living cells. Summary Table: Differences between Diffusion, Osmosis, and Active Transport. shane thorne nxtWebbActive transport: moving against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy.
