Which biomolecule plays a major role in muscle development by providing amino acids for building and repairing muscle tissue?

• A. Proteins
• B. Nucleic acids
• C. Carbohydrates
• D. Lipids

Answer: (A)

Verified step by step guidance

1. Understand the role of biomolecules in the body, focusing on their primary functions related to muscle development and repair.
2. Recall that proteins are made up of amino acids, which are the building blocks necessary for constructing and repairing muscle tissue.
3. Recognize that nucleic acids (DNA and RNA) are primarily involved in genetic information storage and transfer, not directly in muscle repair.
4. Know that carbohydrates mainly provide energy, and lipids serve as long-term energy storage and structural components of cell membranes, but neither directly supply amino acids for muscle repair.
5. Conclude that proteins are the biomolecules that play the major role in muscle development by providing the amino acids needed for building and repairing muscle tissue.
