What is Metabolism? Definition & Types | Short Notes

In this article we will discuss about what is metabolism and types of metabolism

What is Metabolism?

• Set of chemical reactions that occur within a living organism
• Thousands of chemical reactions needed to keep your body as alive and healthy.
• Most of chemical reactions are multi step reaction called pathway

Types of Metabolism

I) Catabolism

• Breaking down of complex molecules into simpler molecules
• Degradation pathway
• This metabolic process releases energy
• Example: Cellular respiration & Digestion of food

II) Anabolism

• Formation of complex molecules from simpler molecules
• Bio-synthetic Pathway
• This metabolic process requires energy
• Example: Photosynthesis, Protein & DNA Synthesis
