Question

part e
tertiary structure is not directly dependent on ______.

• bonds between sulfur atoms
• ionic bonds
• hydrophobic interactions
• hydrogen bonds
• peptide bonds

Explanation:

To solve this, we analyze each option:

• Bonds between sulfur atoms (disulfide bonds) stabilize tertiary structure.
• Ionic bonds, hydrophobic interactions, and hydrogen bonds all contribute to tertiary structure folding.
• Peptide bonds link amino acids in the primary structure (the sequence of amino acids), not directly to tertiary structure (the 3D folding of the polypeptide chain).

Answer:

E. peptide bonds
