Well, as you probably know,
everything around us is made
up of atoms. Every atom has a
center called a nucleus... and a group
of electrons
revolving around
this nucleus.

* Actually, Electrons fly off only from the central reaction center chlorophyll. The other chlorophyll
molecules act as amplifiers to feed energy into the reaction center, which enables the electrons to detach.
The free electron Ah! I get it now! Yeah!

"electron transport chain!"
This other protein complex is also
embedded in the thylakoid membrane.

and O2 is produced
as a result.
