Methanol and ethanol bind to the same active site on the enzyme alcohol dehydrogenase (ADH) to undergo oxidation, as shown in the equations below. In methanol poisoning, ethanol is given intravenously to prevent the formation of formaldehyde that has toxic effects. In this scenario, what type of inhibitor is ethanol with regard to alcohol dehydrogenase catalyzing the oxidation of methanol? CH3-OH + NAD CH3-CH2-OH + NAD+ H* ADH O a competitive inhibitor HCHO+NADH + H+ ADH CH3-CHO+NADH + O a noncompetitive inhibitor O both a noncompetitive and an irreversible inhibitor O an irreversible inhibitor
