Metabolism is the sum of all the chemical reactions that occur within a living organism. These reactions are organized into interconnected pathways that allow the cell to:
* Obtain and utilize energy: This includes breaking down nutrients to generate ATP (cellular energy) and building complex molecules from simpler ones.
* Synthesize essential molecules: This includes the production of proteins, lipids, carbohydrates, and nucleic acids.
* Eliminate waste products: This includes the breakdown of toxic byproducts and their removal from the cell.
Understanding metabolism is crucial for understanding the fundamental processes of life, and it is a key area of study in biology, biochemistry, and medicine.
