Question

Methanol and ethanol are oxidized by alcohol dehydrogenase. When ethanol is oxidized, it becomes acetaldehyde, which can be converted to acetic acid in the liver. However, when methanol is oxidized, it forms formaldehyde. In methanol poisoning, ethanol is given intravenously to prevent the formation of formaldehyde that has toxic effects. Would ethanol compete for the active site or bind to a different site on the enzyme? Ethanol will compete for the active site on the enzyme. Ethanol will bind to a different site on the enzyme. Would ethanol be a competitive or noncompetitive inhibitor of methanol oxidation? Ethanol is a competitive inhibitor of methanol oxidation. O Ethanol is a noncompetitive inhibitor of methanol oxidation.

Explanation / Answer

part d:

ethanol will compet on the active site on the enzyme.

part e:

ethanol is a noncompetative inhibitor of methanol oxidation.
