In photosystem II, excited electrons are transferred to a molecule called Pheophytin and the ETC of photosystem II. As electrons are excited out of the reaction center; they are replaced during the unique biochemical process of oxidizing and producing gas as a byproduct: glucose; carbon dioxide glucose; oxygen water; oxygen water; carbon dioxide

the electrons of photosystem 2 are excited and transferred to electron carriers. From which molecule or structure do the photosystem 11 electrons originate

The electrons lost during the oxidation of P700 are replaced by electrons from NADPH in the Calvin cycle. Photosystem II is responsible for the oxidation of water to produce oxygen. Carbon dioxide is also involved in the process.
