WebLysosomes are membrane-enclosed organelles that function as the digestive system of animal cells, serving both to degrade materials taken up from outside the cells and to digest the cells’ own worn-out components. They contain about 50 different degradative enzymes, which can hydrolyze proteins, nucleic acids, carbohydrates, and lipids. WebThe main characteristic of lysosomes is the battery of hydrolytic enzymes inside them. There are around 50 enzymes that are capable of degrading a wide range of biomolecules. These include nucleases, proteases and phosphatases (which remove phosphate groups from phospholipid mononucleotides and other compounds). hrutan logga in epost
