If the enzyme changes the active site, the rate of reaction will undergo which of the following changes?
Correct answer: A. Decrease
- A. Decrease
- B. Increase
- C. Remains same
- D. Both A and B
Explanation
If the active sites is altered, the substrate cannot fit into the active site of the enzyme and the rate of reaction will decrease.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
