Answer:
Denaturation
Explanation:
Enzymes are a type of protein, and like all other proteins, their structure is a complicated fold of chemical bonds. This form is highly sensitive to the environment, especially when this environment changes in pH, UV radiation, salt concentration, and temperature. In extremes, these environmental factors will cause the bonds holding the protein together to break down, thus unfolding the elaborate amino acid chain, renduring the enxyme useless. This "break-down" is called denaturation.
