Before we kick off this whole Photosynthesis thing we just need to clarify what exactly this mess is

Photosystem II laaa

This bad boy isn’t as complicated as he looks, he’s a Photosystem (Photsystem II to be exact) and basically it’s just a collection or pigments and proteins arranged in a certain way. The green stringy things you see in this diagram are chlorophyll.

In the Light Dependent reactions of Photosynthesis there are two of these photosystemy things involved - Photosystem II and Photosystem I (imaginative names), both of which are located in the Thylakoid Membrane of a chloroplast


Photosystem II also contains what is known as the Oxygen Evolving Complex which does just what it says on the tin - produces Oxygen, Protons & and Electrons from the photolysis of water molecules.
