Water molecule
Photosystem II
Water is split to have its electrons replace the excited electron of chlorophyll, then enters photosystem II.
The water molecule is split at the beginning of the light reaction, specifically in photosystem II. This splitting of water releases electrons, protons, and oxygen as byproducts, which are essential for the rest of the light-dependent reactions to occur.
In a photosystem, light energy is absorbed by pigments to excite electrons, which then pass through an electron transport chain. This creates a proton gradient across the thylakoid membrane, which drives ATP synthesis. The electrons eventually reduce NADP+ to NADPH, which is used in the Calvin cycle for carbon fixation.
First of all it's not photosynthesis II, its photosystem II. well basically, the hydrogen atom within the water molecule loses its electrons and the electrons basically travels through all the photosytems via electron transport chains, towards the NADP Reductase where NADP+ is attached with the electrons from the hydrogen atoms of the water molecule to form NADPH
Water. H2O.
Photosystem II
Light from the sun
During photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The oxygen is a byproduct of the photosynthesis process. It is released into the atmosphere as a waste product.

NADPH is the other molecule produced in the second stage of photosynthesis, known as the light-dependent reactions. Both ATP and NADPH are essential for the production of sugars in the Calvin cycle, which is the third stage of photosynthesis.

oxygenOxygen gas is the product of photosynthesis. It comes from the water being split at photosystem II.
In the process of photosynthesis, the most oxygen is produced during the light-dependent reactions, specifically in the photosystem II complex where water molecules are split to release oxygen as a byproduct.
Chlorophyll p680 loses an electron from the primary electron acceptor, which is a nearby molecule in the photosystem II complex. The chlorophyll then receives an electron from the water molecules that are split during the light-dependent reactions of photosynthesis.
