Methyl alcohol, also known as wood alcohol, is a common solvent and paint remover. It is poisonous if accidentally swallowed. The enzyme alcohol dehydrogenase in the liver converts methyl alcohol into formaldehyde, which then gets converted into a toxic

product. Grain alcohol, ethyl alcohol, is also acted upon by alcohol dehydrogenase. One antidote for methyl alcohol poisoning is to make a person drink a lot of ethyl alcohol. This blocks the active site of the enzyme so that it can't bind to and break down the methyl alcohol. In this capacity, the ethyl alcohol is acting as a/an: A) competitive inhibtor. B) precursor. C) coenzyme. D) allosteric regulator.
