Proteins are large bio-molecules and macro-molecule. Consisting of one or more chains of amino acids residues. It performs a vast array of functions within living organism. A linear chain of amino acid residues is called polypeptides and protein contains at least one polypeptide.

Answer:

<u>Temperature</u> is most likely the reason of protein unfolding (denaturation).

Explanation:

In the figure attached, coiled (3-dimensional) protein structure is changed to 2 dimensional structure in which protein is unfolded. This is most likely the result of heating proteins which destroys the hydrogen bonds and non-polar hydrophobic interactions that are necessary to establish the tertiary structure of proteins. Principally, increased temperature results in the increased kinetic energy of atoms within a molecule. If the amount of heat is sufficient to break the hydrogen bonds, protein molecule can unfold to 2D structure as shown in the figure.
