A denatured protein has lost its _______.

a. hydrogen bonds c. function
b. shape d. all of the above

Summary Introduction

Introduction:

Proteins are the polypeptide chains that are made up of amino acids. An amino acid contains an amine group, carboxyl group, and a variable group. The linkage that bonds two amino acids is known as a peptide bond.

Explanation of Solution

Reason for correct answer:

Option d. is given as “all of the above”.

When a protein is exposed to the high pH and high temperature then this disrupts the hydrogen bonds. The disruption of hydrogen bonds is responsible for denaturation of the protein. Hydrogen bonds within the protein maintain its shape so; the shape would be lost by a denatured protein. If the shape of the protein is lost then it results in the dysfunction of the protein.

Reason for incorrect answer:

Option a. is given as, “hydrogen bonds”.

When a protein is exposed to the high pH and high temperature then the hydrogen bonds disrupted due to the shift in conditions...
