The location of PS-I and PS-II is somewhat common that both are found in the thylakoid membrane. Conclusion. Therefore, we can conclude that the photosystem I and photosystem II plays a fundamental role in trapping photons of selective wavelength and channelizing it to the active reaction centre.

Meanwhile, photons are also being absorbed by pigment molecules in the antenna complex of Photosystem I and excited electrons from the reaction center are picked up by the primary electron acceptor of the Photosystem I electron transport chain. The electrons being lost by the P700 chlorophyll a molecules in the reaction centers of Photosystem I are replaced by the electrons traveling down The Photosystem I Reaction Center Biochemically-purified preparations of PSI reaction centers contain about 100 molecules of chlorophyll a. The reaction center chlorophyll in this photosystem, called P700 after the wavelength where absorption of a photon causes bleaching of absorbance, was proposed to be a dimer of chlorophylls based on the optical properties of synthetic chlorophyll dimers.

In photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In photosystem I, the electron comes from the chloroplast electron transport chain. The two photosystems oxidize different sources of the low-energy electron supply, deliver their energized electrons to different places, and respond to different wavelengths of light.

Photoexcited electrons travel through the cytochrome b6f complex to photosystem I via an electron transport chain set in the thylakoid membrane. A stromal side view of the structure of the cyanobacterial photosystem II (PSII) dimer. The polypeptide. chains are shown at lower contrast to reveal the chromophores; PsbB ( PsbB) and PsbC ( PsbC Photosystem II is the first link in the chain of photosynthesis. It captures photons and uses the energy to extract electrons from water molecules. These electrons are used in several ways. First, when the electrons are removed, the water molecule is broken into oxygen gas, which bubbles away, and hydrogen ions, which are used to power ATP synthesis.

Later, photosystem II was discovered and found to be earlier in the electron transport chain. But it was too late, the name stuck. Electrons first travel through photosystem II and then photosystem I. The Electron Transport Chain

Overall input light energy, H2O. b. 2000-05-01 2006-02-01 2009-05-26 Previous work in our laboratory revealed localized synthesis of photosystem II subunits in a discrete “translation zone” in the chloroplast of the unicellular green alga Chlamydomonas reinhardtii. However, it is unknown whether the translation zone organizes the synthesis and assembly of photosystem I subunits or chlorophyll biosynthesis. PHOTOSYSTEM II. PSII is a multisubunit protein complex located in the thylakoid membranes of all types of plants, algae, and cyanobacteria (Barber 2003).At its heart is the reaction center (RC) core, where light energy is converted to electrochemical potential energy and where the water-splitting reaction occurs.
