(Phys.org)—Piece by piece, the circuit diagram for electron transport in the mitochondria has come closer to completion. Each new structure obtained for any of the five respiratory complexes further ...

Energy is the basis of life, and all organisms depend on mechanisms of energy transformation for growth and reproduction. Living beings get their energy through cellular respiration. In eukaryotes, ...

In addition to nutrients, at the other end of the chain, playing a crucial role in the ETC regulation, is oxygen. On the one hand, oxygen availability determines the ETC function as the final electron ...

UC Davis plant biologists have resolved the structure of proteins vital to energy production in mung beans. Understanding these proteins gives insight into basic plant biology, stress responses, and ...

New research outlines discoveries on the complex I (NADH:ubiquinone oxidoreductase), one of the largest membrane-bound enzymes in the cell, powers ATP synthesis in mammalian mitochondria by using the ...
