Break down various biomolecules it engulfs
- Lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). The enzymes responsible for this hydrolysis require an acidic environment for optimal activity.

What is the function of lysosome in eukaryotic cells?
A lysosome (/ ˈ l aɪ s ə ˌ s oʊ m /) is a single membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that digest many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins and its lumenal proteins.
Mar 15, 2019 · Lysosomes are small cell organelles that digest waste and superfluous cell fragments. They have a simple structure of an outer membrane and an acidic interior fluid. They use enzymes from the endoplasmic reticulum to break down complex proteins and organelles. They are important for cell metabolism, immune response and disease prevention.
