Q.49 Activation energy for the acid-catalyzed hydrolysis of sucrose is 6.22 kJ mol-1, while the activation energy is only 2.15 kJ mol-1 when hydrolysis is catalyzed by the enzyme sucrase. Explain.

Enzymes, the biocatalysts reduce the magnitude of activation energy by providing an alternative path. In the hydrolysis of sucrose, the enzyme sucrose reduces the activation energy from 6,22 kJ mol-1 to 2.15 kJ mol-1.
