Chapter 19, Problem 19.23QP

Interpretation Introduction

Interpretation:

The substrates have to be matched to their corresponding enzymes.

Concept Introduction:

The enzymes are essentially the biocatalysts present in all living systems. Each enzyme catalyzes a characteristic reaction within the biological system. They are classified on the basis of the substrate on which they act or the reaction that they catalyze.

Based on their specific role they are classified into six major classes. These are:

• Ligases: The enzymes that connect two molecules via covalent bonds are termed as ligases.
• Isomerases: The enzymes that catalyze the isomerization reactions are termed as isomerases.
• Lyases: Enzymes that catalyze the cleavage of bonds are called lyases.
• Hydrolases: These enzymes catalyze the cleavage of bonds via hydrolysis present in biological systems.
• Transferases: These enzymes are involved in the transfer of various functional groups such as methyl, acetyl group,  or phosphate group.
• Oxidoreductases: As the name suggests, these catalyze the oxidation and reduction reactions that occur in living systems.
