How Mitochondria Control Your Metabolism | Dr. Jared Rutter
Sep 7, 2026 · 2h 3m
Summary
Andrew Huberman interviews Dr. Jared Rutter, a leading expert on mitochondrial biology, to explore how mitochondria function beyond simple energy production. They discuss the endosymbiotic origin of mitochondria, the spatial distribution of these organelles, and the critical metabolic fork where pyruvate is converted into either ATP for energy or biomass for cell growth. The conversation also covers how insulin signals coordinate cellular responses during fed states and how mitochondrial dysfunction contributes to aging and disease.
