The mechanism of proton pumping by the mitochondrial electron transport chain complexes is still enigmatic after decades of research. Recently, there has been interest in in silico Markov state models to model the mitochondrial pumping complexes at the microscopic level, and this chapter describes the methods of constructing and simulating such models.
