what is mitochondrial biogenesis
Mitochondrial biogenesis is the process by which new mitochondria are formed in the cell. Mitochondrial biogenesis is activated by numerous different signals during times of cellular stress or in response to environmental stimuli.The mitochondrion is a key regulator of the metabolic activity of the cell, and is also an important organelle in both production and degradation of free radicals.he master regulators of mitochondrial biogenesis appear to be the peroxisome proliferator-activated receptor gamma (PGC) family of transcriptional coactivators, including PGC-1Î±, PGC-1Î², and the PGC-related coactivator, PRC.
