"Hydrogen ions flow from the thylakoid down a concentration gradient through ATP synthase channels into the stroma. ADP is converted to ATP."

Explanation: The electron transport chain pumps H+ into the thylakoid lumen, creating a proton gradient. H+ diffuse back into the stroma through ATP synthase (down their gradient), driving ATP synthesis from ADP + Pi.
