Membrane transport proteinsare proteins located in cell membranes, which form an intricate network of channels, pumps and transmembrane systems that transfer nutrients, drugs, metabolism products, toxic substances, macromolecules, signal molecules, electrons and many other cellular componentsdetermining with its operation the molecular compositions and the energy state of the cells.There areinflux transport proteins, that is, the entry of the component into the interior of the cell, andeffluxthat expel molecules from the interior of cells.There is passive transport and active transport – against gradient – that needs coupling of a system that provides energy in the form of ATP.Genetic polymorphisms can alter the structure of transporter proteins and alter their activity.
