Trace the path of an electron from its origins atthe reaction center of photosystem II to its final electronacceptor at the end of photosystem I. Be able to name the mainmolecules involved in the process (this does not include theindividual molecules within the ETCs). Describe any actual‘work’ that the electron does on its journey. Selectone location in this process of linear electron flow, and describethe free energy level, entropy level, and potential to do work ofthe electrons at that location relative to an adjoining location inthe path. Finally, explain how electrons are replaced at thereaction center pigment molecules, and describe the role that REDOXreactions play in the process of electrons moving through thechains.
