Autophagy, being the degradation of cytoplasmic components as well as other organelles, is generally done with the lysosomes. The lysosomes, contain enzymes (hydrolase and others) to digest these worn out, damaged, or infected parts, which keeps the cell healthy and clean. mTOR regulates this process (mammalian target of rapamycin). Lysosomes do carry out a similar procedure to autophagy. It is called autolysis, and that is when the lysosome, excretes all of its digestive juices into the cell. It is like a self-destruct and the entire cell is condemned to a digestive end. Do not worry it only applies to damaged cells.
