Most vitamins __________.

• A. are used as building blocks for the body
• B. function as coenzymes in the body
• C. are carbohydrates
• D. are metabolized to make ATP

Answer: (B)

Verified step by step guidance

1. Understand the role of vitamins in the body: Vitamins are organic compounds that are essential for normal growth and nutrition, usually required in small quantities in the diet because they cannot be synthesized by the body.
2. Identify the function of coenzymes: Coenzymes are non-protein compounds that are necessary for the functioning of an enzyme. They assist enzymes in catalyzing reactions by carrying chemical groups between enzymes.
3. Recognize that many vitamins act as coenzymes: Many vitamins, particularly B vitamins, serve as coenzymes or precursors to coenzymes in various metabolic processes.
4. Differentiate between the options: Analyze each option to determine which accurately describes the role of vitamins. Consider that vitamins are not typically used as building blocks, carbohydrates, or directly metabolized to make ATP.
5. Conclude that the primary role of most vitamins is to function as coenzymes, facilitating various biochemical reactions in the body.
