  1. Question 1

    Q1. A globular protein folds into its final functional three-dimensional shape. Which types of bonds are responsible for maintaining this tertiary structure?

    • A) Peptide bonds only
    • B) Phosphodiester bonds
    • C) Disulfide and ionic bonds
    • D) Glycosidic linkages

    Answer: Disulfide and ionic bonds

    Explanation: The tertiary structure of proteins is maintained by hydrogen, ionic, and disulfide bonds, whereas primary structure relies solely on peptide bonds.
