Which of the following reactions is not enzyme-mediated in biological system ?

A

Dissolving `CO_(2)` in water

B

Unwinding the two strands of DNA

C

Hydrolysis of sucrose

D

Formation of peptide bond

Text Solution

Verified by Experts

The correct Answer is:
A
`CO_(2)` gets dissolved in water, a reaction which is not always catalysed by any enzyme. Unwinding and winding of the two strands of DNA is catalysed by the enzyme topoisomerase. Hydrolysis of sucrose is regulated by sucrase. Peptide bonds are formed by the action of enzyme peptidyl transferase.
