WebDec 10, 2024 · A drastic change in temperature, pH or chemical environment or chemical solution, denatures enzymes. Denatured enzymes are not in their natural form and no longer have a functional active site. WebIf the temperature goes too high, the patient’s brain enzymes can denature (get malformed) which can cause delirium and can even be life-threatening. Doctors have also long been concerned with the opposite extreme when the body temperature is too low (hypothermia). This is equally dangerous and also can be life-threatening.
