Electrons are released into the electron transport system.

Explanation: Light excites electrons in PSII’s chlorophyll, which are passed to the primary electron acceptor and down the electron transport chain. PSII replaces those electrons by splitting water, producing O2 and H+ (protons) in the thylakoid lumen — not creating water or releasing hydrogen as waste.
