Mitochondria are the “power plants” of complex cells. In order to provide the cell with energy they need protein building blocks, which are imported from the outside. Over billions of years the “protein import machines” necessary for this process have developed differently than previously assumed, as biochemists have discovered. This also casts a new light on the evolution of complex cells.
