20. Many people die each year from ingesting antifreeze solutions. Antifreeze contains ethylene glycol, which the human body converts to oxalic acid in the presence of the enzyme alcohol dehydrogenase. Oxalic acid exists in crystalline form and these crystals can severely damage kidneys. Ethanol is administered to victims with ethylene glycol poisoning because ethanol binds to the active site of alcohol dehydrogenase, inhibiting the formation of oxalate crystals. How would you classify ethanol in this scenario?

a) allometric inhibitor of ethylene glycol

b) allosteric inhibitor of ethylene glycol

c) cofactor of ethylene glycol

d) competitive inhibitor of ethylene glycol

e) covalent inhibitor of ethylene glycol
