Lock and Key model was explained by:
Correct answer: B. Emil Fischer
- A. Koshland
- B. Emil Fischer
- C. De Duve
- D. Golgi
Explanation
The lock and Key model was given by Emil Fischer in 1890.According to this model, the active site is a rigid structure. As one specific key can open only a single lock, in the same way, a specific enzyme can transform a specific substrate into the product(s).Example: Urease is the enzyme that follows this model. This model explains the specificity of enzyme action.

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.
