We propose a physical mechanism of conformation-induced proton pumping in mitochondrial Complex I. The structural conformations this protein are modeled as the motion piston having positive charges on both sides. A negatively charged electron attracts piston, moving other end away from site, thereby reducing its energy and allowing to populate site. When escapes, elastic forces assist return in...
The respiratory chain and oxidative phosphorylation are of utter importance for a cell’s metabolism. Here, the energy won from ingested food is being converted into our body’s energy unit (adenosine triphosphate). As the name respiratory chain suggests, oxygen also plays an important role. The following article will explain how exactly this complex mechanism works and which substances may disab...

The primary recognized function of cytochrome c is to act as an electron carrier transferring electrons from complex III to complex IV in the respiratory chain of mitochondria. Recent studies on cell apoptosis reveal that cytochrome c is responsible for the programmed cell death when it is released from mitochondria to cytoplasm. In this study we present evidence showing that cytochrome c plays...
The complexes of the electron transport chain associate into large macromolecular assemblies, which are believed to facilitate efficient electron flow. We have identified a conserved mitochondrial protein, named respiratory supercomplex factor 1 (Rcf1-Yml030w), that is required for the normal assembly of respiratory supercomplexes. We demonstrate that Rcf1 stably and independently associates wi...
