Metabolism

Introduction

Metabolism refers to all chemical reactions that occur in a living organism.
The processes in metabolism involve the conversion of food into energy in the form of ATP, and the formation of carbohydrate, protein, lipid and nucleic acid.

Types of Metabolism in a Cell

Catabolism

Catabolism is the process of breaking down complex substances into simple substances.
This reaction releases energy.
For example, the breakdown of glucose during cellular respiration to generate energy.
Generally, catabolic reactions are as follows:
- A \(\rightarrow\) B + C, where A is the substrate and B + C is the product.

Anabolism

Anabolism is the process of synthesising complex molecules from simple molecules.
This reaction uses or absorbs energy.
For example, the formation of glucose during photosynthesis.
Generally, anabolic reactions are as follows:
- A + B \(\rightarrow\) C, where A + B is the substrate and C is the product.
