active transportation is the one that requires energy. passive transportation doesn't require energy and particles move because of differences of concentration - it's diffusion and osmosis. most common energy source in cells is ATP, also ADP and AMP. active transportation also requires special proteins in cell membrane. those proteins use energy to transport iones and molecules from one side of membrane to another.
