According to_model, the active site of enzyme is modified as the substrate interacts with enzyme.
Correct answer: A. Induced fit
- A. Induced fit
- B. Emil Fischer
- C. Lock and key
- D. Fluid mosaic
Explanation
According to the induced fit model, the active site of the enzyme undergoes a conformational change or modification as the substrate interacts with the enzyme. This change allows for a better fit between the enzyme and substrate, enhancing the catalytic activity. This concept was proposed by Daniel Koshland in 1958.

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.
