where water oxidation at the donor side of photosystem II (PSII) provides electrons for the reduction of protons by H(2)ase downstream of photosystem I. This

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. Two families of reaction centers in photosystems exist: type I reaction centers (such as photosystem I (P700) in chloroplasts and in green-sulphur bacteria) and type II reaction centers (such as photosystem II (P680) in chloroplasts and in non-sulphur purple bacteria). Photosystem 2: The main function of the photosystem 2 is ATP synthesis and hydrolysis of water. Electron Replacement.

The main difference between the two is their order in the photosynthesis process. Although it seems to go against logical reasoning, photosystem II begins the process of photosynthesis by removing an electron from water molecules and breaking it down to oxygen and hydrogen. The excited electron produces ATP as it returns to its rest state.

Treatment of lamellar fragments with neutral detergents releases these particles, designated photosystem I and photosystem II, respectively. Subsequent harsher treatment (with charged detergents in the last video we learned a little bit about both photosynthesis it and we know in very general terms it's the process where we start off with photons and water and carbon dioxide and we use that energy and the photons to fix the carbon and now there's this idea of carbon fixation is essentially taking carbon in a gaseous form in this case carbon dioxide and fixing it into a solid structure 2016-05-18 · The structure of plant photosystem I super-complex at 2.8 Å resolution. eLife 4, e07433 (2015) PubMed Central PubMed Google Scholar 31.
