Question

Who first used the term enzyme?
A. Sumner
B. Kuhne
C. Thompson
D. Garnier

Answer 1

Hint: Enzymes can be defined as complex biological catalysts produced by living organisms in cells to regulate various physiological processes in the body. Thousands of chemical reactions take place in the body of a living organism. The scientist which first used the term enzyme discovered protein-digesting enzymes trypsin.

Complete answer: Enzymes are soluble colloidal organic catalysts that are formed by living cells and catalyze certain biochemical reactions, reducing their activation energy. Enzymes are proteins that are synthesized in living cells and catalyze or accelerate thermodynamically possible reactions, therefore the reaction rate corresponds to the biochemical process necessary to maintain the state of the cell. Sometimes also referred to as organic catalysts or biocatalysts.
Sumner- James Butcheler Sumner is an American chemist. He discovered that enzymes can crystallize, and for this, he received the Nobel Prize in Chemistry with John Howard Northrop and Wendel Meredith Stanley. He was also the first to prove that enzymes are proteins.
Kuhne- Kuhne's original work falls into two main groups. The term "enzyme" was introduced by Kuhne as a catalytically active substance, formerly called ferments. He discovered an enzyme used to digest the protein trypsin.
Garnier-Christian Garnier is a geographer and French linguist best known for developing a systematic way of writing place names.
So, the correct answer is “Option B”.

Additional Information:
Enzymes that act outside living cells are called exoenzymes, for example, enzymes found in digestive juices and lysozyme in tears. Enzymes that function in living cells are known as enzymes such as Krebs cycle enzymes and glycolytic enzymes.

Note:
The real enzyme was discovered by Buchner when he accidentally discovered that sugar fermentation is caused not only by living yeast cells but also by yeast extract. The extract contains the biocatalyst required for this process. Buchner also isolated the first enzyme. There are many enzymes because each biochemical reaction is catalyzed by one enzyme.
