What is the immediate product of the electron transport chain harnessing energy from electron movement?

Answer

Pumping hydrogen ions (H+) into the thylakoid lumen

The energy released as high-energy electrons move down the electron transport chain is captured to actively pump hydrogen ions from the stroma into the thylakoid lumen, establishing an electrochemical gradient.
