About this document
Cell Transport: Active & Passive Processes by gavinhagerty709 is a document available to read on EtoBox.
Passive transport uses diffusion and osmosis to move particles with the concentration gradient, requiring no energy. Active transport moves particles against the gradient using protein pumps and chemical energy from ATP. Diffusion equalizes particle concentrations across membranes. Osmosis moves water across selectively permeable membranes toward lower solute concentrations. Active transport uses protein pumps and ATP to move particles against gradients through membranes.
