Albinism is a congenital disorder resulting from the lack of which enzyme?

Explanation

Albinism is a genetic condition characterized by the absence of melanin, the pigment responsible for coloration in the skin, hair, and eyes. This condition results from mutations in the gene responsible for producing tyrosinase, an enzyme critical for melanin synthesis. In albinism, the gene's mutation leads to a nonfunctional tyrosinase enzyme, preventing melanin production.Option A, Tyrosinase, is correct because it is the enzyme whose deficiency directly causes albinism. Option B, Xanthine oxidase, is unrelated to melanin production and instead affects purine metabolism. Option C, Catalase, is involved in breaking down hydrogen peroxide and is not linked to melanin or albinism. Option D, Fructokinase, affects fructose metabolism and is unrelated to the condition in question.
