Which term refers to the nutrients that build and repair body tissues?

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

Answer: (A)

Proteins are the nutrients that build and repair body tissues. They are made of amino acids, including essential ones that the body can’t make on its own and must come from food. Those amino acids are the building blocks for structures like muscles, skin, and connective tissue, and they also form enzymes, hormones, and antibodies that keep the body functioning. Because tissues constantly wear down and grow, getting enough protein is essential for growth, healing after injury, and everyday maintenance. Fats store energy and help with insulation and the absorption of fat-soluble vitamins, but they aren’t the main building blocks for tissues. Carbohydrates mainly provide the body's quick energy. Vitamins support many metabolic processes but don’t become the structural components of tissues themselves.
