Question

In the below reactions, enzyme A and enzyme B respectively are:

• A. Invertase and Amylase
• B. Amylase and Invertase
• C. Invertase and Zymase
• D. Zymase and Invertase

Answer 1

The correct option is C

Invertase and Zymase

Option C is correct:

In the given reactions both reactions contain different enzymes:

1. The enzyme A is invertase, it converts sucrose into glucose + fructose (monosaccharides).
2. It is used in the hydrolysis of sucrose.
3. The enzyme B is zymase, it converts glucose into ethanol + carbon dioxide.
4. It is used in the formation of alcohol in the beverage industry.

Explanation of incorrect option:

Option A: Invertase helps in breakdown of sucrose into glucose and fructose, and amylase helps in breakdown of starch into glucose.

Option B: Amylase helps in breakdown of starch into glucose, and invertase helps in breakdown of sucrose into glucose and fructose.

Option D: Zymase helps in breakdown of glucose into ethanol and carbon dioxide, and invertase helps in breakdown of sucrose into glucose and fructose.

Final answer: Thus, option C is correct.
