Women have a greater BAL than men of the same weight because women have less __________.Alcohol dehydrogenaseBloodMuscle massBody fat

To analyze the question of why women have a greater blood alcohol level (BAL) than men of the same weight, we need to consider the physiological differences between genders.

Analysis of Options:

1. Alcohol dehydrogenase: This is an enzyme responsible for breaking down alcohol in the body. Women generally have lower levels of alcohol dehydrogenase, resulting in higher BAL after consuming the same amount of alcohol as men.

2. Blood: This option is not relevant, as blood volume does not sufficiently explain the differences in BAL between genders.

3. Muscle mass: Muscle contains more water than fat, which means men, who generally have more muscle mass, will have a lower concentration of alcohol in their bloodstream compared to women of the same weight.

4. Body fat: Women typically have a higher percentage of body fat than men, which affects the distribution of alcohol since alcohol is water-soluble but not fat-soluble.

Conclusion:

Women have a greater BAL than men of the same weight primarily because they have less alcohol dehydrogenase, as this leads to less alcohol being metabolized in the body. Thus, the correct answer is:

Alcohol dehydrogenase.
