Question

phenomenal passage: lysosomes — the cell’s cleanup crew
lysosomes are small, membrane - bound organelles found in animal cells. they contain powerful digestive enzymes that break down waste materials, damaged cell parts, and large molecules such as proteins, fats, and carbohydrates. think of lysosomes as the cell’s recycling center—they help keep the cell clean and balanced by digesting materials the cell no longer needs.
when a lysosome fails to produce one of its necessary enzymes, certain substances cannot be broken down. over time, these substances build up to harmful levels, damaging the cell. this condition leads to lysosomal storage diseases, such as tay - sachs disease. healthy lysosomes are essential for cell maintenance, growth, and survival.

a. the cell becomes stronger
b. macromolecules accumulate to toxic levels
c the nucleus stops working
d. the cell divides faster

1. which of the following best describes lysosomal storage diseases?

b. they result from missing or faulty lysosomal enzymes
c. they help the cell digest faster
d. they prevent energy formation in mitochondria

1. lysosomes are often called the cell’s:

a. powerhouse
b. brain
c cleanup crew
d. transport system

1. in which type of cell are lysosomes most commonly found?

a. plant cells
b animal cells
c. bacterial cells
d. fungal spores

Explanation:

1. The passage clearly states that lysosomes are responsible for digesting and recycling materials in the cell.
2. Lysosomes contain digestive enzymes for breaking down waste and cell parts.
3. When a lysosome lacks an enzyme, substances cannot be broken - down and accumulate to harmful levels.
4. Lysosomal storage diseases result from missing or faulty lysosomal enzymes.
5. The passage refers to lysosomes as the cell's cleanup crew.
6. Lysosomes are small, membrane - bound organelles found in animal cells.

Answer:

1. Lysosome
2. C. Breaking down waste and cell parts
3. B. Macromolecules accumulate to toxic levels
4. B. They result from missing or faulty lysosomal enzymes
5. C. Cleanup crew
6. B. Animal cells
