Answer:
The correct answer is option c). "Defective enzymes result in the accumulation of potentially toxic substances".
Explanation:
Lysosomal storage diseases (LSDs) are a group of rare metabolic disorders that have a genetic influence and are, most of time, autosomal recessively inherited. The molecular basis of the diseases are an accumulation of potentially toxic substances due to the presence of defective enzymes. In fact, LSDs are often triggered by a single defective enzyme that is required for lipids metabolism.
