Summary Introduction

Introduction:

Anabolism is the synthesis of large or complex molecules from smaller units, and it requires energy for this process. In catabolic pathways, large molecules (nutrients) are broken down by enzymes and produce smaller units. They are used as precursor metabolites of anabolic reactions. In catabolic reactions, cells use enzymes (catalysts) and derive energy from ATP to produce macromolecules. Hence, enzymes are very crucial for anabolic reactions.
