The number of models that represent enzyme-substrate model is ----
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
There are two main models that represent enzyme-substrate interactions:Lock and key model: This model proposes that the active site of the enzyme has a specific shape that is complementary to the shape of the substrate. Induced fit model: This model proposes that the active site of the enzyme is flexible and can change shape to accommodate the substrate.Therefore, the number of models that represent enzyme-substrate interactions is two, not one, three, or four.

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.
