Electron transport chain
A process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient. / From Wikipedia, the free encyclopedia
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]
