Mitochondria are the central organelle of cellular metabolism. They host key metabolic pathways including the respiratory electron transport chain (ETC) and the Krebs cycle (named after Freiburg scientist Hans A. Krebs). Understanding mitochondria is therefore key to metabolism research. Freiburg Metabolism researchers study the function of ETC complexes, mitochondrial protein import, mitochondrial dynamics and other key aspects of mitochondrial biology. The community is increasingly interested in cell type specific functions of mammalian mitochondrial and their role as signalling hubs.
