<P> Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or , such as in the case of the oxidation of sugars , cellular respiration . In eukaryotes , an important electron transport chain is found in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation through the use of ATP synthase . It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes . In bacteria , the electron transport chain is located in their cell membrane . </P>
