Question

    Match the Column I with Column II and select the correct

    answer using the codes given below: Column I (Molecule) A. Proteins B. Carbohydrates C. Nucleic acids D. Lipids Column II (Product of Digestion) Nitrogenous bases and pentose sugars Fatty acids and glycerol Monosaccharides Amino acids
    A 2 3 1 4 Correct Answer Incorrect Answer
    B 2 1 3 4 Correct Answer Incorrect Answer
    C 4 3 1 2 Correct Answer Incorrect Answer
    D 4 3 2 1 Correct Answer Incorrect Answer

    Solution

    • Proteins (A): Digested into amino acids (4) by enzymes like pepsin and trypsin.
    • Carbohydrates (B): Broken down into monosaccharides (3) like glucose by enzymes such as amylase.
    • Nucleic acids (C): Digested into nitrogenous bases and pentose sugars (1) by nucleases.
    • Lipids (D): Broken down into fatty acids and glycerol (2) by lipases.
    Information Booster:
    1. Digestion involves the breakdown of macromolecules into absorbable units.
    2. Proteins require stomach acids and proteolytic enzymes.
    3. Carbohydrates start digestion in the mouth with salivary amylase.
    4. Lipids are emulsified by bile salts for efficient enzyme action.
    5. Nucleic acids are digested in the small intestine.
