Verified step by step guidance

Understand the context of Tay-Sachs disease: It is a genetic disorder that affects the nervous system, leading to the accumulation of certain substances in the brain.

Identify the substance involved in Tay-Sachs disease: The disease is characterized by the accumulation of gangliosides, which are complex molecules found in nerve cell membranes.

Recognize the enzyme deficiency: Tay-Sachs disease is caused by a deficiency in the enzyme hexosaminidase A, which is responsible for breaking down gangliosides.

Differentiate between the options: Sphingosine, ceramide, dipalmitoyl phosphatidyl choline, and carbohydrates are not the substances that accumulate in Tay-Sachs disease. Gangliosides are the correct answer.

Conclude with the biochemical implication: The inability to degrade gangliosides due to hexosaminidase A deficiency leads to their accumulation, causing the symptoms associated with Tay-Sachs disease.
