Which of the propeies accounts for ethanol's use in ethylene glycol poisoning?

A
Competitive inhibitor of NADPH oxidase
B
Competitive inhibitor of alcohol dehydrogenase
C
Competitive inhibitor of aldehyde dehydrogenase
D
Non-competitive inhibitor of aldehyde dehydrogenase
High-Yield Explanation
Ethanol acts by competing with ethylene glycol for alcohol dehydrogenase, the first enzyme in the degradation pathway. Because ethanol has a much higher affinity for alcohol dehydrogenase, about a 100-times greater affinity, it successfully blocks the breakdown of ethylene glycol into glycoaldehyde, which prevents the fuher degradation.
