In which one of the following enzymes, is copper necessarily associated as an activator
A
Tryptophanase
B
Lactic dehydrogenase
C
Tyrosinase
D
Carbonic anhydrase
Answer
Tyrosinase
Explanation
Solution
In tyrosinase, copper is associated as an activator. Tyrosinase is an oxidase that is the rate-limiting enzyme for controlling the production of melanin. Tyrosinase is a copper-containing enzyme present in plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation. So, the correct answer is 'Tyrosinase'.
