Cell metabolism refers to the complex set of chemical reactions that occur within cells to maintain life. These reactions allow cells to convert food into energy, build and repair cellular structures, and eliminate waste. Metabolism is generally divided into two categories: catabolism, which breaks down molecules to release energy, and anabolism, which uses that energy to create new molecules. In essence, cell metabolism is crucial for growth, reproduction, and overall cellular function. It involves various pathways and enzymes that help regulate these processes. Understanding metabolism is vital for fields like biochemistry and medicine, as it can influence health and disease management.
