What biological factor contributes to men eliminating alcohol faster than women?

The correct answer is that men typically have higher amounts of the dehydrogenase enzyme, which plays a crucial role in the metabolism of alcohol. This enzyme is responsible for breaking down ethanol in the liver. Because men generally have higher levels of this enzyme compared to women, they are often able to metabolize and eliminate alcohol from their systems more quickly.

This biological difference is significant and contributes to the varied effects of alcohol consumption between genders. The variations in enzyme levels can stem from differences in body composition, hormonal influences, and genetic factors, which all play a role in how effectively alcohol is processed in the body. As a result, individuals with higher concentrations of the enzyme may experience a more rapid breakdown of alcohol, leading to differences in blood alcohol concentration and its effects on the individual.

Understanding these biological factors is essential for recognizing how alcohol affects men and women differently, which is important for safe drinking practices and awareness of impairment.
