Lock and key model for enzyme action proposed by Emil Fischer suggests that:
Correct answer: C. Enzymes are restricted to one reaction type
- A. Enzymes are unbiased for substrate
- B. Enzymes can modify their active sites
- C. Enzymes are restricted to one reaction type
- D. Enzymes can catalyze variety of reactions
Explanation
According to lock and key model, every enzyme is specific due to its active site for its substrate. Therefore, every enzyme can convert only its specific substrate into product.

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.
