transport
Cells transport components into and out of cells across the plasma membrane, across membranes (nuclear, organellar) within cells, and as intracellular transport within the cytoplasm. Cellular transport is also referred to a translocation.
Active transport pumps require expenditure of energy, most often in the form of ATP, to transport hydrophilic macromolecules and ions across membranes against chemical or concentration gradients.
