Question

allergic reactions to alcohol characterized by flushing, itching, and rash are linked to overactivity of which substance?
multiple choice
gastric hydrochloric acid
acetyl dehydrogenase enzyme
neurotransmitter dopamine
neurotransmitter serotonin

Explanation:

When alcohol is consumed, it is metabolized. One of the key enzymes in alcohol metabolism is acetyl dehydrogenase enzyme. An issue with this enzyme (such as reduced activity or over - activity in some cases related to genetic variations) can lead to the buildup of acetaldehyde. Symptoms like flushing, itching, and rash are associated with acetaldehyde accumulation. Gastric hydrochloric acid is related to digestion in the stomach and not directly to these alcohol - related allergic - like symptoms. Dopamine is a neurotransmitter involved in reward, motivation, etc., and serotonin is a neurotransmitter involved in mood, sleep, etc., and neither of these neurotransmitters' over - activity is directly linked to these specific alcohol - induced physical symptoms.

Answer:

acetyl dehydrogenase enzyme
