About this Seminar
Dr. Jonas and her team have found a leak channel within the mitochondrial ATP synthase that opens to switch cellular metabolism between oxidative phosphorylation and aerobic glycolysis. These two metabolic states are both required by cells for metabolic flexibility. Oxidative phosphorylation is the most efficient way for cells to produce energy in the form of ATP. Cells sacrifice energy production efficiency for growth and repair since “leak metabolism” speeds macromolecular biosynthesis. Finally, prolonged channel opening leads to cell death by mitochondrial permeability transition.
