Metabolism is the sum of all the chemical reactions in your body. Your body is constantly breaking down and building compounds, a process that creates and uses energy, and sustains life. Metabolism Definition What is metabolism in the body? Metabolism encompasses the various biochemical processes, reactions, and conversions that transform one form of energy to another. Any molecule that’s synthesized or utilized in metabolism is a physically-recognizable form of energy. The basic law of conservation of energy in Physics states that “energy can neither be created nor be destroyed; it can only be transformed from one form to another”. Following this basic rule, we can ... Metabolism refers to all the biochemical processes that occur within living organisms to maintain life. It encompasses the conversion of food into energy, the synthesis of necessary compounds, and the regulation of these processes to ensure homeostasis. Understanding metabolism is crucial for fields such as biochemistry, nutrition, and medicine. Metabolism is how your body turns food and drink into energy for essential functions. Learn about the processes, conditions and factors that affect your metabolism and how to keep it healthy.
