WebMar 23, 2024 · Background Skeletal muscle gradually loses mass, strength, endurance, and oxidative capacity during aging. Studies of bioenergetics and protein turnover show that mitochondria mediate this decline in function. Mitochondria are essential for the production of ATP, which occurs in the cristae, the folds of the inner mitochondrial membrane. WebDec 12, 2024 · When the cell has excess energy, it stores this energy by forming ATP from ADP and phosphate. ATP is required for the biochemical reactions involved in any muscle contraction. As the work of the muscle increases, more and more ATP gets consumed and must be replaced in order for the muscle to keep moving. Because ATP is so important, …
