Energy metabolism is the process by which living organisms convert food into energy for various physiological functions. This process involves the breakdown of carbohydrates, fats, and proteins through a series of biochemical reactions to produce adenosine triphosphate (ATP), the primary source of energy for cells. Energy metabolism plays a crucial role in maintaining the body's energy balance, regulating body weight, and supporting cellular functions such as growth, repair, and reproduction. Research in this area focuses on understanding the mechanisms and regulation of energy metabolism in health and disease, including obesity, diabetes, and metabolic disorders. By studying energy metabolism, researchers aim to develop strategies for improving metabolic health and preventing chronic diseases associated with energy imbalance.
