Abstract: BEC tutorial-Living Communications. Mitochondrial membrane potential and Peter Mitchell’s protonmotive force: elements of the science of bioenergetics. Preceding the EMC 2022 49th European Muscle Conference, Prague, Czech Republic.
The mitochondrial membrane potential is an element of the science of bioenergetics, linked to the control of respiratory flux and related mitochondrial functions. A PubMed search on ‘mitochondrial membrane potential’ yields nearly 40 000 results and 3442 for 2021 (search 2022-07-04), with a linear increase during the past 20 years. Chapter 8 on ‘Protonmotive pressure and respiratory control’ of Mitochondrial Pathways (Gnaiger 2020) introduces a novel perspective on Peter Mitchell’s protonmotive force, which incorporates the mitochondrial membrane potential. If you find the reading is tough, you are not alone. Join this BEC tutorial-Living Communications for an introduction into the relevant concepts of physical chemistry, which differ from misleading chapters in bioenergetics textbooks on potential gradients, Gibbs energy, protonmotive flow and force, and finally protonmotive pressure. This will introduce students (and teachers) to a new understanding of mitochondrial membrane potential and the protonmotive force, connecting the ideal gas equation, osmotic pressure, the Boltzmann constant and gas constant with Fick’s and Einstein’s diffusion equation. If theory gets tough, join for a follow-up retreat.
