Question

The enzyme that converts glucose into ethyl alcohol and carbon dioxide is

• A. invertase
• B. maltase
• C. urease
• D. diastase
• E. zymase

Hint:

Zymase = fermentation enzyme (glucose → alcohol + CO$_2$).

Answer 1

Answer: (E)

Understanding the 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 Final Answer. Only zymase performs fermentation: \[ \boxed{\text{Zymase}} \]
