  1. Question 1

    Q1. When an egg white is cooked, the albumin protein becomes solid and opaque. Which mechanism is occurring during this denaturation process?

    • A) Cleavage of the primary peptide bond sequence
    • B) Disruption of hydrogen and ionic bonds
    • C) Synthesis of new disulfide bridges
    • D) Hydrolysis of the amino acid R-groups

    Answer: Disruption of hydrogen and ionic bonds

    Explanation: Denaturation disrupts secondary and tertiary structures (H-bonds, ionic, etc.) but leaves the primary covalent peptide bonds intact.
