Question

In Photosystem II, an excited electron helps pump hydrogen into the thylakoid. What are the hydrogen ions used for? Explain how this process converts forms of energy.

Answer 1

After the special pair gives up its electron, it has a positive charge and needs a new electron. This electron is provided through the splitting of water molecules, a process carried out by a portion of PSII called the manganese center^9 . The positively charged P680 can pull electrons off of water (which doesn't give them up easily) because it's extremely "electron-hungry."
