My name is Aleksandra Trifunovic, I'm a professor of mitochondria genetics in disease and aging at the University of Cologne in Germany and the title of talk is Mitochondria and Ageing in Model Systems. The Mitochondria are the powerplants of the cells.

Without them we would not be able to sustain any kinds of multicellular life on earth. To function properly, our body in each second needs around three times 10 to the power of 18 molecules of ATP, and that means that our mitochondria produce roughly around 70 kilos of ATP every day. Most of this ATP is consumed by central nervous system and brain in our bodies.

So, although mitochondria is considered as this extremely powerful electric centrals of our body, they actually produce and harbor many other different processes that are essential for our body functioning and homeostasis. So among those, we have fatty acid oxidation, TCA cycle, production of different intermediates like for example, iron-sulphur cluster assembly intermediates or heme synthesis intermediates, also some parts of amino acid synthesis are located inside mitochondria. So, mitochondria are unique in
