To explore the biology of energy, 15 articles from the online Perspectives focus on mitochondria, the cellular organelles that produce most of a body's energy by oxidative phosphorylation. The topics include mitochondial DNA genetics and the heteroplasmy conundrum in evolution and disease, mitochondrial biogenesis through the activation of nuclear signaling proteins, mechanism of mitochondrial fission and fusion, altered sulfide metabolism in ethylmalonic encephalopathy, and the relevance of mitochondial genetics and metabolism in cancer development.
