Method of<unk>  differs throughout tissues depending on two factors; the metabolic needs of the tissue and availability of<unk> . The two ways in which<unk>  can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which on the ion-gradient which is established through the hydrolysis of ATP, known as primary active transport). Active transport is the movement of ions or molecules going against the concentration gradient.
