A disease caused by the absence of a lysosomal enzyme responsible for lipid catabolism:
Correct answer: A. Tay-Sachs disease
- A. Tay-Sachs disease
- B. Phenylketonuria
- C. Klinefelter syndrome
- D. Down syndrome
Explanation
Tay-Sachs disease is a genetic disorder caused by the absence of a vital lysosomal enzyme responsible for breaking down certain lipids. This deficiency leads to the accumulation of lipids in nerve cells, which impairs brain function.
