Match Column I with Column II Column I (Scientist) Column II...
Match Column I with Column II
Choose the correct answer from the options given below:
| Column I (Scientist) | Column II (Discoveries) |
| (A) Edward Buchner | (I). Lock and Key hypothesis |
| (B) Emil Fischner | (II). Induced Fit theory |
| (C) Koshland | (III). and Vmax concept |
| (D) Michaelis -Menten | (IV). Yeast fermentation |
Options
- A(A) - (IV), (B) - (I), (C) - (II), (D) - (III)
- B(A) - (III), (B) - (II), (C) - (I), (D) - (IV)
- C(A) - (II), (B) - (III), (C) - (IV), (D) - (I)
- D(A) - (I), (B) - (IV), (C) - (III), (D) - (II)
Correct answer
A. (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
Step-by-step solution
Edward Buchner discovered that cell-free extracts of yeast could ferment sugar, leading to the discovery of the enzyme complex zymase. Thus, (A) matches (IV).
Emil Fischer proposed the Lock and Key hypothesis in 1894 to explain the specificity of enzymes. Thus, (B) matches (I).
Daniel Koshland proposed the Induced Fit theory in 1958, which states that the binding of a substrate induces a conformational change in the active site of the enzyme. Thus, (C) matches (II).
Leonor Michaelis and Maud Menten developed the Michaelis-Menten equation in 1913, which introduced the concepts of the Michaelis constant (K_m) and maximum velocity (V_\max) in enzyme kinetics. Thus, (D) matches (III).
The correct matching is (A) - (IV), (B) - (I), (C) - (II), (D) - (III).
Answer: (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
