Correct option is B
The correct combination of metals in the active sites of these enzymes is as follows:
Acetylene hydratase contains tungsten (W).
Urease contains nickel (Ni) as its active site metal.
Carboxypeptidase is a zinc-containing enzyme, with zinc (Zn) as its catalytic metal ion.
Sulfite oxidase contains molybdenum (Mo) as the active site metal.
Information Booster:
Acetylene hydratase utilizes tungsten for the hydration of acetylene.
Urease catalyzes the hydrolysis of urea into carbon dioxide and ammonia.
A carboxypeptidase is a protease enzyme that hydrolyzes (cleaves) a peptide bond at the carboxy-terminal (C-terminal) end of a protein or peptide.
Sulfite oxidase requires molybdenum for the oxidation of sulfite to sulfate.
