Biogenesis of mitochondria notes

WebMitochondria are cellular compartments of eukaryotes that are enclosed by two membranes. They are often called the powerhouses of the cell because of their central role in energy transduction. Fundamental metabolic processes such as oxidative phosphorylation, iron-sulfur cluster biogenesis, beta-oxidation of fatty acids, the citric … 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.
