Question:
The enzyme that converts glucose into ethyl alcohol and carbon dioxide is
The enzyme that converts glucose into ethyl alcohol and carbon dioxide is
Show Hint
Zymase = fermentation enzyme (glucose → alcohol + CO$_2$).
Updated On: May 8, 2026
- invertase
- maltase
- urease
- diastase
- zymase
Show Solution

The Correct Option is
Solution and Explanation
Concept:
Fermentation is the biochemical process where glucose is converted into ethanol and carbon dioxide:
\[
C_6H_{12}O_6 \rightarrow 2C_2H_5OH + 2CO_2
\]
This process is catalyzed by a group of enzymes.
Step 1: Identify enzyme responsible.
• Zymase is a complex enzyme present in yeast
• It catalyzes fermentation of glucose
Step 2: Check other options.
• Invertase → sucrose breakdown
• Maltase → maltose breakdown
• Urease → urea decomposition
• Diastase → starch digestion
Step 3: Final conclusion. Only zymase performs fermentation: \[ \boxed{\text{Zymase}} \]
