The process whereby ions such as sodium and potassium are passed across cell membrane in human cells is known as membrane transport system. This process is regulated by a series of mechanism which involves the creation of electrochemical gradients across the plasma membrane of the cells. The membrane transport system is powered by energy in form of ATP. The three major electron transport system in humans are passive transport (diffusion), osmosis and facilitated diffusion.
