Photosystem II is the first protein complex in oxygenic photosynthesis's light-dependent processes. It is found in plants, algae, and cyanobacteria's thylakoid membrane.
- The thylakoid membrane, which is a part of the chloroplast in plant cells, is where Photosystem I and Photosystem II are found.
- The products of the light dependent processes are delivered to the light independent reactions as ATP and NADPH.
- Water molecules are divided into oxygen atoms and hydrogen ions when photosystem II pulls replacement electrons from them.
- The thylakoid compartment retains the hydrogen ions from the water.
- High energy electrons are transferred from Photosystem II to Photosystem I in the electron transfer chain.
- The high-energy electrons in the photosystem received energy from sunlight while they were there.
- Photosystem I releases high-energy electrons into the atmosphere.
- The high energy electrons join NADP+ and a hydrogen ion after going via an electron transfer chain.
- ADP and Pi are combined to create ATP with the help of hydrogen ions passing via the ATP synthases.
So to conclude with we can say that the initial protein complex in the light dependent processes of oxygenic photosynthesis is called photosystem II. It may be found in plants, algae, and cyanobacteria's thylakoid membrane.
