Which of the following changes could lead to loss of enzymatic function?
- A
Decrease in activation energy of the reaction
- B
Increase in enzyme concentration
- C
Change in overall enthalpy of the reaction
- D
Increase in pH of the reaction
A. Decrease in activation energy of the reaction (Incorrect): This would enhance the reaction rate, but it won't cause loss of enzymatic function.
B. Increase in enzyme concentration (Incorrect): Higher enzyme concentration can accelerate the reaction, but it won't lead to loss of enzymatic function.
C. Change in overall enthalpy of the reaction (Incorrect): Enzymes facilitate reactions without altering the overall enthalpy, so changes in it won't cause loss of enzymatic function.
D. (Correct) Enzymes are pH and temperature sensitive., and only function in optimal ranges of these conditions.
This would enhance the reaction rate, but it won't cause loss of enzymatic function.
