Which nutrient is made up of amino acids and used for building, maintaining, and repairing body tissues?

• A. Protein
• B. Carbohydrates
• C. Fat
• D. Vitamins

Answer: (A)

Proteins are made up of amino acids and serve as the primary building blocks for body tissues. They are essential for constructing and repairing structures like muscles, skin, bones, and connective tissue, and they also perform roles as enzymes, hormones, and components of the immune system. While carbohydrates and fats provide energy and vitamins support metabolism, they do not constitute the main structural components of tissues. That combination of being built from amino acids and used to build, maintain, and repair tissues is what makes protein the correct choice.
