Consequences of Protein Denaturation

In biological systems, macromolecules play critical roles in cell structure and function. Proteins, as an example, are composed of amino acids linked by peptide bonds. Consider a protein that undergoes denaturation due to high temperatures. Denaturation can disrupt the secondary and tertiary structures of the protein without breaking its primary amino acid sequence. Which of the following statements best describes the consequences of this denaturation process on protein function?
