Activation energy for the acid catalysed hydrolysis of sucrose is `6.22 kJ mol^(-1)`, while the activation energy is only `2.15 kJ mol^(-1)` when hydrolysis is catalysed by the enzyme sucrase. Explain.

Explanation

Enzymes as we know, are biocatalysts in energy nature. In the presence of the enzyme surface, the hydrolysis of sucrose requires less activation as compared to acid catalysed hydrolysis.
