Question
Explain the mechanism of enzyme action.
✓

Answer

→Enzymes are needed only in small quantities for the progress of a reaction.
→Similar to the action of chemical catalysts enzymes are said to reduce the magnitude of activation energy.
→For example activation energy for acid hydrolysis of sucrose is 6.22 KJ/mol, while the activation energy is only 2.15 KJ/mol. when hydrolysed by the enzyme sucrase.
