Correct answer: D. Formation of the enzyme-substrate complex
- A. Change in pH of the surroundings
- B. Change in the charge of the active site
- C. Change in temperature
- D. Formation of the enzyme-substrate complex

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.
