Metabolic processes are the chemical reactions that occur within living organisms to maintain life. These processes convert food into energy, allowing cells to grow, reproduce, and respond to their environment. Metabolism is generally divided into two categories: catabolism, which breaks down molecules to release energy, and anabolism, which uses energy to build complex molecules. These processes are essential for various functions, including digestion, respiration, and cellular repair. Enzymes play a crucial role in facilitating these reactions, ensuring they occur efficiently and at the right pace. Overall, metabolic processes are vital for sustaining life and supporting overall health.
