|
Which of the following is an inaccurate statement about denaturation.
|
|
Denaturation can be reversible.
|
|
|
Denaturation affects primary, secondary, and tertiary structure but not quaternary structure.
|
|
|
Denaturation can occur as a result of inadequate pH levels.
|
|
|
Denaturation disrupts all hydrogen bonding.
|
Explanation:
Detailed explanation-1: -Denaturation sabotages the quaternary structure by dissociate the protein subunits and/or disrupt the spatial arrangement of proteins subunits.
Detailed explanation-2: -Primary structure, such as the sequence of amino acids held together by covalent peptide bonds, is not disrupted by denaturation.
Detailed explanation-3: -During the denaturation of proteins, the secondary and tertiary structures get destroyed and only the primary structure is retained. Covalent bonds are broken and interaction between amino-acid chains gets disrupted. This results in the loss of biological activity of the proteins.
