The availability of wideband receivers altogether with the high collecting area of ALMA will easily cover large spectral regions, allowing us to create full molecular line surveys of a wide variety of extragalactic objects, far from our present reach. This observations will provide a full chemical description of a large number of galaxies with different morphologies and evolutionary stages. The recently published 2 mm line survey towards the starburst galaxy NGC 253 has shown the need of chemical templates within the Galaxy in order to fully understand molecular emission within the nuclear region of galaxies. It will be shown how the study of the chemical complexity of molecular cloud prototypes within the Galactic Center region may provide a key information to determine the heating mechanisms of molecular material in the nuclei of galaxies. In the nearby future this chemical studies will be further extended to the high- z universe and will be particularly important in sources such as submillimeter galaxies, not easily observable in other frequency ranges.
