Questions and Answers

What type of interactions contribute to the tertiary structure of a polypeptide?

Hydrogen bonds and ionic bonds

Hydrophobic interactions and van der Waals interactions

Covalent bonds and disulfide bridges

All of the above (correct)

What is the purpose of hydrophobic interactions in the tertiary structure of a polypeptide?

To bring nonpolar amino acid side chains together at the core of the protein

To exclude water molecules from the protein's interior

To stabilize the overall shape of the protein

All of the above (correct)

How do disulfide bridges form in a polypeptide?

When van der Waals interactions occur between nonpolar amino acid side chains

When two hydrogen-bonding amino acid side chains interact

When two positively charged amino acid side chains form an ionic bond

When two cysteine monomers with sulfhydryl groups on their side chains are brought close together by the folding of the protein (correct)
