Arginase, an enzyme used in the final step of the urea cycle, contains this metal. A certain compound
 containing both potassium and this metal is known as Condy's crystal and in organic chemistry is used as
 an alternative to osmium tetroxide in a basic solution to convert an alkene to a 1,2-diol, or as an alternative
 to chromium-based complexes to react an alcohol to a carboxylic acid. The oxygen evolving complex in
 chloroplasts has a center with calcium and this metal. In the body, this metal is paired with iron in a class of
 superoxide dismutase found in the mitochondria. This metal is central to the testing of alkenes in Baeyer's
 reagent, which involves the reduction of its +7 oxidation state to its +2 oxidation state. For 10 points, name
 this transition metal with chemical symbo
