CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
Amino acids
Proteins: Fundamental Building Blocks
Proteins are vital macromolecules that perform numerous functions in living organisms, including catalyzing metabolic reactions, providing structural support, and aiding in transport.
Identifying Protein Monomers
The basic units, or monomers, that link together to form long chains, creating proteins, are known as amino acids. Each protein is composed of a specific sequence of these amino acids.
Evaluating the Options
- Nucleotides: These are the monomers that make up nucleic acids (DNA and RNA).
- Lactic acid: This compound is a product of anaerobic respiration and is not a component of proteins.
- ATP (Adenosine Triphosphate): This molecule is the main energy currency of the cell and is not a building block for proteins.
Thus, amino acids are the correct building blocks of proteins.
