Tay-Sachs disease is a neurological disorder in which a defective enzyme prohibits the hydrolysis of phospholipids called gangliosides. Enzymes that breakdown molecules in a cell are typically found in which organelles?

The correct answer is lysosomes

Explanation:

Tay-Sachs disease is a genetic metabolic disorder in which a lipid called GM2 ganglioside builds in the brain which results in spasticity and death in childhood.

This disease is also known as lysosomal storage disease. Lysosomes are the major organelle that contains enzymes to breakdown molecules. In Tay-Sachs disease deficiency of hexosaminidase A occurs in lysosomes and this enzyme is needed to breakdown fats.  

So due to this deficiency, it results in the accumulation of fats in the brain and spinal cord causing Tay-Sachs disease.
