It gets ionized.
What happens to the chlorophyll molecule after losing a pair of electrons?
It gets oxidized.
Where do electrons move along a chain of carriers during oxidation-reduction reactions?
Thylakoid membranes
What creates and maintains a concentration gradient of protons across the thylakoid membrane?
Photolysis of water
