Question

Protein can be denatured by

• A. Carbon dioxide
• B. Carbon monoxide
• C. Heat
• D. Oxygen

Answer 1

The correct option is C Heat

Proteins are building blocks of the body. The proteins are made up of amino acids. The amino acids are linked together by peptide bonds to form a protein. Peptide bond is formed by the linkage of the carboxyl group of one amino acids with the amino group of the amino acids. On heating the peptide bonds breaks and the protein gets denatured as heat increases the kinetic energy of the molecules and leads to breaking of the bonds.

So, the correct answer is option C.
