The electron transport chain is the path in which the electrons travel during cellular respiration. The electron transport system is the set of proteins and other cellular câ¦omponents that are involved in the electron transport chain. For example, the both aerobic and anaerobic organisms, there are different electron transport systems and this influences the path electrons take.
