Which of the following is true?
Some studies show that women eliminate alcohol slower than men do.
Older people tend to have higher BAC levels.
People who are more muscular absorb less alcohol than those with a higher percentage of fat.
The Correct Answer and Explanation is:
The correct answer is: Some studies show that women eliminate alcohol slower than men do.
Explanation:
The rate at which alcohol is metabolized in the body varies between individuals and is influenced by several factors, including biological sex, age, body composition, and overall health. Among these factors, one of the most significant differences in alcohol metabolism is related to biological sex.
Why Women Eliminate Alcohol Slower than Men:
- Differences in Enzyme Activity: Women generally have lower levels of alcohol dehydrogenase (ADH), the enzyme responsible for breaking down alcohol in the stomach and liver. This leads to slower alcohol metabolism in women compared to men. Men tend to have higher levels of ADH, allowing them to metabolize alcohol more efficiently.
- Body Composition: Women typically have a higher percentage of body fat and a lower percentage of lean muscle mass than men. Alcohol is water-soluble, so individuals with more body water (such as those with more muscle mass) tend to have a lower blood alcohol concentration (BAC) compared to those with higher fat content. Since fat does not absorb alcohol well, women, on average, may experience higher BAC levels than men after consuming the same amount of alcohol.
- Smaller Body Size: On average, women tend to be smaller in body size compared to men, which means that the same amount of alcohol will be distributed in a smaller volume of blood, resulting in higher BAC levels.
Older People Tend to Have Higher BAC Levels:
This statement is not always true. As people age, their liver function may decline, and they may have less body water and muscle mass. This can slow alcohol metabolism and result in higher BAC levels than younger individuals. However, other factors, such as medication use and overall health, also play a role.
Muscle Mass and Alcohol Absorption:
This statement is incorrect. Individuals with more muscle mass absorb alcohol in the same way as those with more fat. However, those with more muscle mass typically have lower BAC levels after drinking because muscle tissue contains more water, which helps dilute alcohol.
