Induced fit theory of enzyme action was proposed by

Options

A. Koshland
B. Fischer
C. Hershet and Chase
D. Sumner.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientist who proposed the Induced Fit Theory of enzyme action.

2. **Identifying the Options**: The options provided are:
- A) Kochland
- B) Fisher
- C) Herschel and Chase
- D) Seminar

3. **Recalling the Induced Fit Theory**: The Induced Fit Theory is a concept in biochemistry that describes how enzymes and substrates interact. Unlike the Lock and Key model, which suggests that the enzyme's active site is a perfect fit for the substrate, the Induced Fit Theory proposes that the active site of the enzyme changes shape to fit the substrate upon binding.

4. **Identifying the Scientist**: The Induced Fit Theory was proposed by the scientist named **Daniel E. Koshland Jr.** in 1958.

5. **Selecting the Correct Option**: Based on the information, the correct answer is option A) Kochland.

6. **Final Answer**: The Induced Fit Theory of enzyme action was proposed by **Kochland**.
