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 Mi
