Which term is a B vitamin essential for metabolism?

• A. Biotin
• B. Beriberi
• C. Ascites
• D. Atherosclerosis

Answer: (A)

Biotin is a B vitamin essential for metabolism because it acts as a coenzyme for several carboxylase enzymes that drive key steps in processing carbohydrates, fats, and proteins. As a cofactor, biotin helps enzymes add carbon dioxide in reactions like turning pyruvate into oxaloacetate (glucose production) and supporting fatty acid synthesis and odd-chain amino acid metabolism. This makes biotin vital for turning dietary nutrients into usable energy and building blocks the body needs. Beriberi is a disease caused by deficiency of thiamin (vitamin B1), not biotin. Ascites is the abnormal buildup of fluid in the abdomen, often from liver disease or heart failure. Atherosclerosis is the hardening and narrowing of arteries due to plaque buildup, not related to a specific vitamin.
