Multiple Choice
In the context of lysosomal and degradation pathways, which organelles are often described as the cell's recycling centers because they digest macromolecules and damaged organelles into reusable building blocks?
A
Golgi apparatus
B
Peroxisomes
C
Ribosomes
D
Lysosomes
Verified step by step guidance1
Understand the role of lysosomes in the cell: Lysosomes contain hydrolytic enzymes that break down macromolecules such as proteins, lipids, carbohydrates, and nucleic acids into their basic building blocks.
Recognize that lysosomes also digest damaged or obsolete organelles through a process called autophagy, helping to recycle cellular components.
Compare lysosomes with other organelles listed: Golgi apparatus is involved in modifying and packaging proteins, peroxisomes detoxify harmful substances, and ribosomes synthesize proteins but do not digest materials.
Identify that the term 'cell's recycling centers' refers to organelles that degrade and recycle cellular waste, which matches the function of lysosomes.
Conclude that lysosomes are the organelles responsible for digesting macromolecules and damaged organelles into reusable building blocks, making them the cell's recycling centers.
