Protein Folding

Why is water important as a solvent in protein folding?

• Water breaks down protein structure

• Water stabilizes protein structure

• Water provides energy for protein folding

• Water prevents protein folding

What factors contribute to the overall stability of a folded protein?

• Formation of hydrogen bonds between backbone atoms and side chains.

• Formation of hydrophobic interactions

• All of the above

What is the process of hydrolysis?

• The breakdown of a polymer into monomers that produces water.

• The formation of a polymer from monomers that requires water.

• The breakdown of a polymer into monomers using water.

• The breakdown of a monomer into a polymer that produces water.

How does water help to stabilize a protein's tertiary structure? Pick the two answers that apply.

• By forming hydrogen bonds with the side chains of the amino acids

• By solvating the protein and reducing its overall energy

• By increasing the protein's entropy

What are hydrophobic interactions in protein folding?

• Interactions between water molecules and the nonpolar regions of the protein

• Water forcing the hydrophobic regions of proteins towards the inside of the protein.

• Interactions between water molecules and the polar regions of the protein

• Interactions between the hydrophilic side chains of the protein and water molecules

What is the most important driving force in protein folding?

• Hydrophobic interactions between the protein and water molecules

• Hydrogen bonding between water molecules

• Ionic interactions between the protein and water molecules

• Hydrophilic interactions between the protein and water molecules

What is the role of water in the synthesis of biomolecules?

• Water is used in dehydration synthesis to break down polymers into monomers

• Water is used in hydrolysis reactions to produce water as a result of the breakdown of a monomer

• Water is used in hydrolysis reactions to break down polymers into monomers

• Water is used in dehydration synthesis to produce water as a result of the breakdown of a monomer

What is the role of hydrophobic interactions in protein folding?

• Hydrophobic interactions provide energy for protein folding

• Hydrophobic interactions prevent protein folding

• Water forces the hydrophobic regions to come together therby shaping the protein.

• Hydrophobic interactions break down protein structure

What happens to hydrophobic regions during protein folding?

• They form hydrogen bonds with other amino acids

• They form hydrophobic interactions with water molecules

• They move away from the water to form a hydrophobic interaction.

• They form hydrogen bonds with water molecules
