Question

The enzyme that converts glucose to ethyl alcohol is

• A. Maltase
• B. Zymase
• C. Diastase
• D. Invertase

Answer 1

The correct option is B

Zymase

The correct option is B.

Explanation of the correct option:

1. Zymase basically converts the glucose into the ethyl alcohol through the process of fermentation.
2. It occurs naturally in yeasts.
3. Fermentation denotes the energy-yielding pathway which involves the anaerobic breakdown of the molecules (Example- Glucose).

Explanation of the incorrect options:

Option A:

1. Maltase is also known as malt sugar which is a disaccharide that is formed by the two units of the glucose that are joined with an $\mathrm{\alpha }$ -bond.
2. Maltase just break down maltose into the glucose.

Option C:

1. Diastase is basically the mixture of amylase enzymes.
2. It catalyzes the breakdown of the starch into maltose.

Option D:

1. Invertase is basically an enzyme that is produced by yeast.
2. Invertase is actually an enzyme that will catalyze the breakdown of sucrose into fructose and glucose.

Final answer: The enzyme that converts glucose to ethyl alcohol is zymase.
