WebAbstract. B ecause of their symbiotic origin, mitochondria are often regarded as semiauto-nomous, bacteria-like structures suspended in the cytoplasm. Nevertheless, the structure and distribution of mitochondria are dependent on the activity and architecture of the whole cell, and the synthesis of mitochondrial components depends almost ... Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles. Mitochondrial biogenesis is activated by numerous different signals during times of cellular stress or in response to environmental stimuli, such as aerobic exercise.
