Question

Albinism is due to hereditary deficiency of enzyme

• A. Amylase
• B. Carbonic anhydrase
• C. Acetyl choline esterase
• D. Tyrosinase

Answer 1

The correct option is D Tyrosinase

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, as in the blackening of a peeled or sliced potato exposed to air. It is found inside melanosomes which are synthesized in the skin melanocytes. In humans, the tyrosinase enzyme is encoded by the TYR gene. A mutation in the tyrosinase gene resulting in impaired tyrosinase production leads to type I oculocutaneous albinism, a hereditary disorder.

So, the correct answer is 'Tyrosinase'.
