Which outcome occurs when excessive mechanical stress breaks hydrogen bonds within a protein molecule?

A)Denaturation and loss of function
B)Increased catalytic activity
C)Formation of disulfide bridges
D)Enhanced protein-protein interaction

💡 Explanation

When excessive mechanical stress breaks hydrogen bonds, the tertiary structure of the protein unfolds causing denaturation, because hydrogen bonds maintain the correct shape required for its function. Therefore denaturation occurs, rather than increased activity, disulfide bridge formation, or enhanced interaction which require specific enzymatic reactions or conditions.
