Electron transport chain

The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. The NADH and succinate generated in the citric acid cycle are oxidized, providing energy to power ATP synthase.

An electron transport chain (ETC) is how a cell gets energy from sunlight in photosynthesis. Electron transport chains also occur in reduction/oxidation ("redox") reactions, such as the oxidation of sugars in cellular respiration.

In aerobic respiration, each molecule of glucose leads to about 34 molecules of ATP (Adenosine triphosphate) being produced by the electron transport chain. This is by far the most productive part of respiration.[1]
