A modified form of the Lock and Key model was proposed by:
Correct answer: A. Koshland
- A. Koshland
- B. Fischer
- C. Watson
- D. Rosalind Franklin
Explanation
A modified form of the lock and key model is called the induced fit model, which was proposed by Koshland. According to this model, when a substrate combines with an enzyme, it induces changes in the enzyme structure.

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.
