Definitions

Exosome complex below. The exosome complex (or PM/Scl complex, often just called the exosome) is a multi-protein complex , capable of degrading various types of RNA s. Exosome complexes can be found in both eukaryotic cells and archaea , while in bacteria a simpler complex called the degradosom more

Equipartition theorem

Equipartition theorem peptide . The jittery motion is random and complex, and the energy of any particular atom can fluctuate wildly. Nevertheless, the equipartition theorem allows the average kinetic energy of each atom to be computed, as well as the average potential energies of many vibrationa more

Helicobacter pylori

Helicobacter pylori Helicobacter pylori () is a Gram-negative , microaerophilic , and acidophilic bacterium that infects various areas of the stomach and duodenum . Many cases of peptic ulcer s, gastritis , duodenitis , and perhaps some cancer s are caused by H. pylori infections. However, man more

Oxidative phosphorylation

Oxidative phosphorylation in the mitochondrion is the site of oxidative phosphorylation in eukaryote s. The NADH and succinate generated in the citric acid cycle is oxidized, releasing energy to power the ATP synthase . Oxidative phosphorylation is a metabolic pathway that uses energy released b more
