Alcohol dehydrogenase

  1. Sep 8, 2011 #1
    1. The problem statement, all variables and given/known data

    Alcohol dehydrogenase is an enzyme that catalyzes the catabolism of ethanol (an alcohol). In order to function, the enzyme requires a zinc ion (Zn++).
    What is the best description of Zn++ in relation to alcohol dehydrogenase?

    The zinc ion also acts as an enzyme.
    The zinc ion carries substrates to the enzymes.
    The zinc ion is one of the products of the reaction catalyzed by this enzyme.
    The zinc ion helps the enzyme interact with ethanol at the active sites.
    The zinc ion is a coenzyme.

    2. Relevant equations



    3. The attempt at a solution

    I know zinc is a cofactor not a coenzyme and it doesn't carry the substrate to the enzyme but i can't figure out what the best answer is
