True False Save Question 8 (1 point) ? Denaturing a protein changes its primary structure. True False Save Question 9 (1 point) d Proteins can be denatured by acid, base, heat, heavy metals, alcohols, or even by vigorous shaking. True

Answer 1

The primary structure of proteine consists the amino acid sequence of the polypeptide chains. The secondary structure of proteins results from hydrogen bonds. The tertiary structure of proteins is due to interactions between amino acid side chains.

Q7. Hydrolysis of proteine will break polypeptide chain. And hence it will change the primary structure of proteine. So the given statement is true.

Q8. Denaturation reactions are not strong enough to break the peptide bonds. Thus it will not make any changes to primary structure of proteine. Statement is false.

Q9. Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure. However, applying some external force in the form of heat, shaking can break the secondary and tertiary structures. So the statement is true.
