Many people of Asian descent have ______ levels of alcohol dehydrogenase activity.Multiple choice question.very lownormal to highvery highnormal to low

Break Down the Problem

1. Identify the context of the question, which involves the enzymatic activity of alcohol dehydrogenase in people of Asian descent.
2. Analyze the potential answer choices to find the correct descriptor of the enzyme activity levels.

Relevant Concepts

1. Alcohol dehydrogenase is an enzyme involved in the metabolism of alcohol.
2. Variations in enzyme activity can depend on genetic factors, particularly among different ethnic groups. Research highlights that many individuals of Asian descent, particularly East Asians, often have genetic variations that reduce the activity of this enzyme.

Analysis and Detail

1. Individuals of East Asian descent frequently have lower levels of alcohol dehydrogenase activity due to a genetic predisposition. This leads to differences in alcohol tolerance and metabolism, causing many to experience undesirable effects when consuming alcohol.
2. Based on studies, it's understood that while some may have normal levels, a significant portion reports very low activity, which can be linked to flushing reactions after alcohol consumption.

Verify and Summarize

• The correct choice should reflect the limited activity of alcohol dehydrogenase commonly observed in this demographic.

Final Answer

Many people of Asian descent have very low levels of alcohol dehydrogenase activity.
