The process of creating energy-storing compounds in cells, particularly through the synthesis of ATP (adenosine triphosphate), is known as cellular respiration. This multi-step metabolic pathway involves the breakdown of glucose and other organic molecules to release energy, which is then utilized to form ATP. Cellular respiration can occur through aerobic processes, requiring oxygen, or anaerobic processes, occurring without oxygen. This energetic transformation is fundamental for life, as ATP produces the energy necessary for various cellular functions, including growth, repair, and maintenance of cellular activities.
