Question

multiple choice question enzymes that help to break down macromolecules within the cell are missing in the lysosomes of individuals suffering from: sickle-cell anemia, cystic fibrosis, tay-sachs disease, huntington’s disease

Explanation:

• Sickle - cell anemia is a disorder related to abnormal hemoglobin in red blood cells, not lysosomal enzyme deficiency.
• Cystic fibrosis is caused by a mutation affecting the CFTR protein, leading to issues with mucus production, not lysosomal enzyme problems.
• Tay - Sachs disease is a lysosomal storage disorder where the enzyme needed to break down gangliosides (a type of macromolecule) in lysosomes is missing.
• Huntington’s disease is a neurodegenerative disorder caused by a trinucleotide repeat in the huntingtin gene, not related to lysosomal enzymes.

Answer:

C. Tay - Sachs disease
