Which of the following is an enzyme lacking disease?
Correct answer: A. PKU
- A. PKU
- B. Alkaptonuria
- C. Anuria
- D. Dluria
Explanation
Phenylketonuria (PKU) is the correct answer as it is a genetic disorder caused by a deficiency of the enzyme phenylalanine hydroxylase (PAH). This enzyme is critical for the metabolism of the amino acid phenylalanine. Without this enzyme, phenylalanine accumulates and can lead to neurological damage. Alkaptonuria also involves an enzyme deficiency, but it is not the enzyme referenced in the question, and anuria and dluria are unrelated to enzyme deficiencies.
