Biomolecules · Class 12 · JEE Main Previous Year Question
In the above reactions, the enzyme A and enzyme B, respectively are:
- a
Amylase and Invertase
- b
Invertase and Amylase
- c✓
Invertase and Zymase
- d
Zymase and Invertase
Invertase and Zymase
Step 1: Sucrose Breakdown — The hydrolysis of sucrose into glucose and fructose is catalyzed by the enzyme (also called sucrase).
Step 2: Ethanol Fermentation — The conversion of glucose (a monosaccharide) into ethanol and carbon dioxide is a fermentation process catalyzed by .
Step 3: Sequence — Therefore, Enzyme A is and Enzyme B is . This matches option (c).
Remember: Yeast is a common source for both these enzymes used in traditional fermentation.
