Correct answer: A. Emil Fischer
- A. Emil Fischer
- B. Koshland
- C. Robin Williams
- D. Rudolph Virchow
Explanation
Emil Fischer proposed the lock-and-key model, in which the substrate has a shape complementary to the enzyme's relatively rigid active site. The likely alternative is Koshland, who proposed the induced-fit model in which the enzyme changes shape as the substrate binds.
