Organic molecules needed by the body in very small amounts are known as what?

• A. Vitamins
• B. Minerals
• C. Carbohydrates
• D. Proteins

Answer: (A)

Vitamins are organic molecules required in very small amounts to support many metabolic processes. They’re carbon-containing helpers that often serve as cofactors or coenzymes, enabling enzymes to carry out essential reactions for energy production, synthesis of molecules, and tissue maintenance. Because they’re needed in tiny quantities, they’re classified as micronutrients and must come from the diet (with a few exceptions where the body can make small amounts). This distinguishes them from minerals, which are inorganic elements; and from carbohydrates and proteins, which are macronutrients required in larger amounts for energy and growth.
