Who coined the term ‘Enzyme’ for first time ?

The correct answer is (a) Buchner.

Buchner was a German chemist who was the first to isolate and crystallize an enzyme, in this case,zymase, which is responsible for fermentation. He coined the term “enzyme” in 1878 to describe these biological catalysts.

Sumner was an American chemist who was the first to crystallize a protein, in this case, urease. He won the Nobel Prize in Chemistry in 1937 for his work on enzymes.

Kuhne was a German physiologist who coined the term “biochemistry” in 1877. He was also the first to propose that enzymes are proteins.

Huxley was an English biologist who is best known for his work on evolution. He did not coin the term “enzyme.”
