In a “Bionic” device created by Dan Nocera, this reaction is driven by a self-assembling cobalt-phosphate cluster and a nickel-molybdenum-zinc catalyst. The center of an enzyme that catalyzes this reaction (15[1])is coordinated by the aspartate and glutamate residues of D-sub-1 and CP-sub-43. Titanium dioxide nanoparticles were found to catalyze this reaction on their surfaces by Honda and Fujishima. (15[1])This reaction’s reactant and molecules like sulfuric acid are added to the middle cylinder and a current is run through the system to produce this reaction’s products in a three-cylinder apparatus named for (*) Hoffman. This reaction is driven by the movement of electrons from S0 to S4 in a complex named for the evolution of one of this reaction’s products. For 10 points, name this reaction in which a namesake molecule is broken down into hydrogen and oxygen gas. (0[1]-5[1])■END■
