Understanding Metabolism: Anabolism and Catabolism

**Metabolism:** The totality of the chemical reactions and physical changes that occur in living

organisms, comprising **anabolism** and **catabolism** → The enzyme reactions of synthesis,

breakdown and interconversion of essential biomolecules - **Catabolism → T**he metabolic breakdown of complex

substances into smaller products (including the breakdown of carbon compounds with the liberation

of energy for use by the cell or organism) - **Anabolism →** The energy requiring part of metabolism

in which simpler substances are transformed into more complex ones (as in growth or other biosynthetic

processes) !(attachment:453f385b-50c6-48a4-85eb-1fd85da4c041:1000000913.png)
