Bioenergetics is the study of how living organisms convert energy from food into usable forms. It focuses on the biochemical processes that occur within cells, particularly how ATP (adenosine triphosphate) is produced and utilized. This energy is essential for various cellular functions, including growth, repair, and movement. In bioenergetics, the role of mitochondria is crucial, as these organelles are often referred to as the "powerhouses" of the cell. They generate most of the cell's ATP through processes like cellular respiration, which involves breaking down glucose and other nutrients. Understanding bioenergetics helps researchers explore metabolic diseases and develop energy-related therapies.
