|
|
A denatured protein cannot carry out its biological functions
|
|
|
Chemicals and heat can disrupt the bonds and bridges that hold polypeptides in their tertiary structure
|
|
|
A protein that has been denatured by heat of chemicals will usually return to its normal state after the denaturing agent has been removed
|
|
|
If the denaturing agent breaks the peptide bonds that hold the amino acid together than the protein will be destroyed
|
Detailed explanation-1: -(i) Denaturation of proteins causes loss of secondary and tertiary structures of the protein.
Detailed explanation-2: -Denaturation does not change the primary structure of protein. The coagulation of egg white on boiling is a common example of denaturation. During denaturation secondary and tertiary structures are destroyed but primary structure remains intact.
Detailed explanation-3: -During the denaturation process of protein, the secondary and tertiary structure of protein will be changed but the peptide bond of the primary structure remains constant. Because, the denaturation reaction is not strong and its energy is not enough to break the peptide bond.
Detailed explanation-4: -Final answer: The wrong statement about the denaturation of proteins is fibrous proteins are converted into globular proteins.
