Which statement is correct regarding the rate of alcohol metabolism in the human body?

• A. The rate of alcohol metabolism increases significantly with higher alcohol consumption.
• B. The rate of alcohol metabolism is constant and independent of the amount consumed.
• C. The rate of alcohol metabolism is primarily controlled by the kidneys.
• D. Alcohol metabolism is faster in women than in men.

Answer: (B)

Verified step by step guidance

1. Understand that alcohol metabolism primarily occurs in the liver, not the kidneys. The liver uses enzymes, mainly alcohol dehydrogenase, to metabolize alcohol.
2. Recognize that the rate of alcohol metabolism is generally constant for most individuals, typically around 0.015 grams per deciliter per hour. This rate does not significantly increase with higher alcohol consumption.
3. Consider the factors that can affect alcohol metabolism, such as genetic variations, liver health, and the presence of food in the stomach, but these do not change the fundamental constant rate of metabolism.
4. Note that while there are differences in alcohol metabolism between men and women, these are due to differences in body composition and enzyme levels, not a faster rate of metabolism in women.
5. Conclude that the correct statement is that the rate of alcohol metabolism is constant and independent of the amount consumed, as it is primarily determined by the liver's enzymatic activity.
