Explore the question in detail with explanation, related questions, and community discussions.
The chief builder of the body is protein. Proteins are fundamental nutrients made up of amino acids, which are the building blocks of tissues, muscles, organs, enzymes, and many other structural and functional components of the human body. Unlike carbohydrates and fats, which mainly serve as energy sources, proteins have a primary role in building and repairing body structures.
Growth and Development:
Proteins are essential during childhood, adolescence, and pregnancy, as the body requires new tissues and cell formation.
Tissue Repair:
Proteins help repair damaged muscles, skin, blood vessels, and internal organs, especially after injuries or illnesses.
Enzymes and Hormones:
Many enzymes and hormones that control biochemical reactions in the body are proteins. For example, insulin (a hormone) and amylase (a digestive enzyme) are protein-based molecules.
Immune System Function:
Antibodies, which protect the body against diseases, are specialized proteins.
Structural Components:
Proteins like collagen, keratin, and elastin form skin, hair, nails, and connective tissues, giving the body shape and strength.
Carbohydrates: Mainly provide energy (glucose) for cells and brain functions.
Fats: Supply energy reserves, insulation, and vitamin absorption, but are not the primary tissue-building nutrient.
While all nutrients are important, proteins are considered the "chief builders of the body" because they directly contribute to body structure, tissue formation, and cellular repair.Hence, the correct answer is Proteins (Option B).
