The function of the enzymes in various chemical reactions:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Act as biological catalysts
Enzymes are biological catalysts. Their primary function in chemical reactions is to:
- Increase the rate of reaction (by lowering the activation energy).
- Not get consumed in the reaction.
- Remain unchanged at the end of the reaction.
- Be highly specific to their substrate.
Why the other options are incorrect:
- Increase activation energy → Wrong. Enzymes decrease activation energy.
- Biochemical enhancers → Not a standard or accurate term in this context.
- Decreases the rate of reaction → Completely wrong. Enzymes increase the rate.
