Question

Cite the name of the enzyme responsible for the following biochemical transformation: \[ C_6H_{12}O_6 (\text{Glucose}) \xrightarrow{\text{Enzyme}} 2C_2H_5OH + 2CO_2 (\text{Ethanol}) \]

• A. Diastase
• B. Maltase
• C. Urease
• D. Xylose

Hint:

In fermentation, the enzyme zymase is responsible for converting glucose into ethanol and carbon dioxide. This reaction is crucial in yeast metabolism.

Answer 1

The Correct Option is D

Step 1: Understanding the Process.
The given reaction represents the fermentation of glucose, where glucose (\(C_6H_{12}O_6\)) is converted into ethanol (\(C_2H_5OH\)) and carbon dioxide (\(CO_2\)).
Step 2: Identify the Biochemical Pathway.
This is a common biochemical process known as fermentation. In this process, glucose is metabolized by yeast or other microorganisms to produce ethanol and carbon dioxide. 
Step 3: Enzyme Catalysis.
The enzyme responsible for this transformation is zymase. Zymase is a complex of enzymes found in yeast that catalyzes the fermentation process. Zymase helps break down glucose into ethanol and carbon dioxide. 
Step 4: Verify the Options.
Option (A) Diastase is involved in the breakdown of starch into maltose but not in fermentation. 
Option (B) Maltase breaks down maltose into glucose but does not catalyze the fermentation process. 
Option (C) Urease is involved in the breakdown of urea, not fermentation. 
Option (D) Xylose is incorrect because it is a sugar, not an enzyme.
Therefore, the correct enzyme for this transformation is zymase, which is involved in the fermentation of glucose.
