A lysosome is a membrane-bound organelle that participates in numerous cell processes and aids in the breakdown of excess, worn-out cell parts.
It is one of the cell's suicidal organelles.
Lysosome formation:
Lysosomes are formed by budding off of the Golgi body, and thus the hydrolytic enzymes contained within them are produced within the endoplasmic reticulum.
The catalysts are labeled with mannose-6-phosphate and transported to the Golgi body in vesicles before being incorporated into the lysosomes.
