What will happen to the pH inside of a thylakoid that is exposed to light?

Question

Quizplus · Accepted Answer

During photosynthesis, light energy is used to split water molecules into oxygen, hydrogen ions (protons), and electrons. The protons are pumped from the stroma into the thylakoid lumen, creating a concentration gradient. When light energy is absorbed by pigments in the thylakoid membrane, the electrons become excited, causing them to move along an electron transport chain, which releases energy used to pump more protons into the lumen. This generates a higher concentration of protons in the lumen compared to the stroma, creating an electrochemical gradient. As a result, the pH inside the thylakoid decreases, becoming more acidic.
