Lysosomes function in:
Correct answer: C. Intracellular digestion
- A. Protein synthesis
- B. Processing of cellular materials
- C. Intracellular digestion
- D. Lipid synthesis
- E. Carbohydrate synthesis
Explanation
Lysosomes are specialized organelles within the cell that contain hydrolytic enzymes capable of breaking down macromolecules like proteins, nucleic acids, lipids, and carbohydrates. Their primary function is intracellular digestion, where they degrade and recycle cellular waste, damaged organelles, and material ingested by the cell. Unlike ribosomes, lysosomes do not synthesize proteins, and they are not involved in lipid or carbohydrate synthesis, which occur in other organelles. Options such as 'protein synthesis', 'lipid synthesis', and 'carbohydrate synthesis' refer to processes that take place outside of lysosomes, highlighting their specialized role in cellular maintenance through digestion.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
