LYSOSOMES Small membrane-bound vesicles that contain digestive (hydrolytic enzymes). The vesicles are released from the GOLGI COMPLEX and are dispersed throughout the cytoplasm. Over 50 different enzymes present. Lysosomes play an important role in the digestion of internalized particles (phagocytosis) and macromolecules (pinocytosis/receptor-mediated endocytosis). Another important function of lysosomes is the digestion and break down of old cellular components, which otherwise tend to accumulate and interfere with proper

Unformatted text preview: cell function. The lysosome membrane itself is able to resist the digestive action of its own enzymes. In addition, when a cell dies, the lysosome membrane breaks down, releasing digestive enzymes into the cytoplasm, where they break down the cell itself. Some forms of tissue damage as well as the aging process may be related to "leaky lysosomes". Whether or not lysosomes are present in plant cells is open to debate....
