How are micronutrients utilized by the body?

• A. In large quantities only
• B. In very small amounts as enzyme cofactors
• C. As primary energy sources
• D. Only during specific life stages

Answer: (B)

Micronutrients, which include vitamins and minerals, are essential for various physiological functions in the body, primarily acting as enzyme cofactors. These substances are required in very small amounts and play critical roles in metabolic processes. For instance, many vitamins are involved in energy production and the synthesis of important biomolecules while minerals such as zinc and magnesium function as cofactors for enzymes, enabling biochemical reactions to occur efficiently. This utilization is crucial for maintaining homeostasis, supporting immune function, and ensuring proper growth and development. The other options describe uses that do not accurately represent the role of micronutrients. For example, saying they are used in large quantities is misleading, as these nutrients are required in much smaller amounts. Additionally, while macronutrients like carbohydrates, proteins, and fats serve as primary energy sources, micronutrients do not provide energy directly. Lastly, indicating that micronutrients are utilized only during specific life stages overlooks their constant necessity throughout a person’s life for overall health and optimal functionality.
