Metabolism encompasses all the chemical processes that occur within a living organism to maintain life. It includes:
* Anabolism: Building up of complex molecules from simpler ones, requiring energy.
* Catabolism: Breaking down of complex molecules into simpler ones, releasing energy.
These processes are essential for:
* Growth and development: Building new cells and tissues.
* Energy production: Providing energy for cellular functions.
* Repair and maintenance: Replacing damaged cells and tissues.
* Waste elimination: Removing waste products from the body.
Therefore, metabolism is a comprehensive term that encompasses the entire spectrum of chemical reactions happening within cells, crucial for sustaining life.
