In mitochondria, the energy released by the complete metabolism of sugars is used extremely efficiently. In the cytoplasm of an animal cell, as an example, for each molecule of glucose that is metabolized, two molecules of ATP are produced as a result of glycolysis. Mitochondria, on the other hand can produce 30 molecules of ATP for each molecule of glucose. The citric acid cycle occurring in the matrix of the mitochondrion produces mobile electrons which are then sent through the mitochondrial electron-transport chain to support the necessary reactions for energy production. These reactions include the conversion of ADP to ATP in a process referred to as oxidative phosphorylation. In the digital video presented above, normal Gray fox lung fibroblast cells (FoLu line) are expressing monomeric green fluorescent protein (mEGFP) fused to the mitochondrial targeting signal from subunit VIII of human cytochrome C oxidase.
