  • play a central
  • Controlled' is not the word I would use (not in most cases of mammalian apoptosis, anyway), since the originating signal that triggers apoptosis of a given cell usually comes from outside the cell, but yes, mitochondria play a central and quite early role in apoptosis. (bio.net)
  • matrix
  • Hydrogen ions from NADH are transferred across from the interior of the mitochondria to the external matrix , generating a potential difference across the internal membrane . (everything2.com)
  • produce
  • The increased ability to produce energy that mitochondria provide is probably one of the reasons for us eukaryotes being up here and prokaryotes never getting round to discovering fire , inventing the wheel , forming civilisation , that sort of thing. (everything2.com)
  • To produce energy, your mitochondria require oxygen from the air you breathe and fat and glucose from the food you eat. (mercola.com)
  • plant
  • The chapters compiled in this detailed collection outline a number of methods used to study plant mitochondria today, starting from the isolation of mitochondria to detailed analyses of RNA, protein, and enzymatic activities. (springer.com)
  • life
  • Dr. Lee Know's book, "Life - The Epic Story of Our Mitochondria", is a really good primer if you want to learn more about this topic after listening to this interview. (mercola.com)
  • years
  • A small protein called cytochrome c, which is normally part of the respiratory chain, was 'to general stupefaction' (I quote a recent paper) discovered, only a few years ago, to be massively released from mitochondria into the cytosol shortly before apoptosis occurs. (bio.net)
  • It is as though mitochondria are biologically immortal (and homeostatically flawless) for billions of years until you and I inherit them, and then go downhill almost instantly (in comparison). (bio.net)
