What would happen to an enzyme if the temperature and ph changed significantly beyond the enzyme's optimum level ?

Enzymes change activity with alterations in pH and temperature. Each enzyme functions  most rapidly at a specific pH optimum. When the pH deviates too greatly from the enzyme's optimum, activity slows and the enzyme may be damaged

Enzymes also have optima for maximum activity. If the temperature rises too much above the optimum, an enzyme's structure will be disrupted and  its activity lost. This phenomenon is known as denaturation and may be caused by extremes of temperature and pH and also by other factors.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
