In a thylakoid membrane preparation, a researcher shines light and measures pH in the thylakoid lumen and stroma. Under illumination, the lumen becomes more acidic than the stroma due to H+ movement associated with electron transport. If the researcher blocks ATP synthase so H+ cannot pass through it, which change is most likely during continued illumination?
