The series of molecules through which excited electrons are passed down thylakoid membrane is called electron transport chain.

In electron transport chain, the transfer of electron occurs from the element which loses electron to the element which receives electron through a membrane like structure called thylakoid membrane . This occurs in redox reaction means one atom is reduced i. e. gain electron and other is oxidized i. e. loses electron.
