what is water oxidized to in photosynthesis

Water-oxidation catalysts mediate the four-electron, four-proton oxidation of water to dioxygen.. Water oxidation is one of the half reactions of water splitting: . S. Lv 7. Trending Questions. Source(s): S. 1 0. The energy of the resulting electrons and protons released during water oxidation is then stored as the biological equivalent of hydrogen. The mechanism by which water is oxidized occurs through a 5 stage Kok cycle illustrated below? Water oxidation is the primary reaction of both natural and artificial photosynthesis. Relevance. Developing active and robust water oxidation catalysts (WOCs) is the key to constructing efficient artificial photosynthesis systems, but it is still facing enormous challenges in both fundamental and applied aspects. Water oxidation is the primary reaction of both natural and artificial photosynthesis. O2. 2H 2 O → O 2 + 4H + + 4e − Oxidation (generation of dioxygen) . Join. In water oxidation, in addition to oxygen release, electrons and protons are also produced. Join Yahoo Answers and get 100 points today. The Sn states in the Kok diagram denote different discrete oxidation states where n the number of oxidative “equivalent” stored in the OEC during cycle progression. what is water oxidized to in photosynthesis? Water is oxidized during photosynthesis.Oxidation number of O changes from -2 to 0. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ask Question + 100. Still have questions? Photosynthetie water oxidation is unique to plants and cyanobacteria, it occurs in thylakoid membranes. 4H + + 4e − → 2H 2 Reduction (generation of dihydrogen) . The role of H2O, or water, in photosynthesis, is essential to ATP, which is the energy process that drives photosynthesis. Favorite Answer. Figure: Kok Cycle. Get your answers by asking now. This transforms the water … Electrons could be used to reduce a variety of molecules such as H 2 O, CO, CO 2 or N 2 to produce useful compounds in artificial photosynthesis . Trending Questions. Solved: During photosynthesis, is oxidized, while is reduced. So this is an oxidation reaction 1 Answer. Contribution of water oxidation to the ATP synthesis. Answer Save. 4.21. Answer: During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), to produce carbohydrates. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. 10 years ago. During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Photosynthesis consumes carbon dioxide and water to create oxygen and organic molecules. It is also important in the making of food; hydrogen atoms found in water make up part of the glucose molecules that plants use as nourishment. 2H 2 O → 2H 2 + O 2 Total Reaction .
