Question

The essential element needed for water splitting in photosythesis leading evolution is

Answer 1

Society’s energy supply problems could be solved in the future using a model adopted from nature. During photosynthesis, plants, algae and some species of bacteria produce sugars and other energy-rich substances (i.e. fuels) using solar energy. A team headed by researchers from the Max Planck Institute for Chemical Energy Conversion in Mülheim an der Ruhr is currently developing experimental methods to ascertain how this process occur in nature. The scientists are investigating a particularly important cofactor involved in photosysthesis, a manganese-calcium complex, which uses solar energy to split water into molecular oxygen. They have determined the exact structure of this complex at a crucial stage in this chemical reaction. This has led to a detailed suggestion as to how molecular oxygen, O2, is formed at this metal complex. Through these new insights into photosynthesis, the scientists have provided a blueprint for synthetic systems that could store sunlight energy in chemical energy carriers.
