- E. Buchner
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Historical background of enzymes.
The study of enzymes began in the 19th century when scientists started understanding biological catalysts.
Step 2: Contribution of W. F. Kühne.
Wilhelm Friedrich Kühne introduced the term “enzyme” in 1877 to describe biological catalysts that act within living organisms.
Step 3: Meaning of enzyme.
The word enzyme means “in yeast,” reflecting early studies on fermentation processes.
Step 4: Analysis of other scientists.
- E. Fischer: Proposed lock and key model.
- D. Koshland: Proposed induced fit model.
- E. Buchner: Demonstrated cell-free fermentation.
Step 5: Logical verification.
Only Kühne is historically credited with coining the term enzyme.
Step 6: Final conclusion.
Therefore, the correct answer is W. F. Kühne.
