Autophagy is induced with in the cytoplasm. And can take place in lysosomes.
Autophagy takes place in the lysosomes of a cell.
Lysosomes are rich in hydrolytic enzymes that can lyse ecery biomolecules including proteins. lysosomes are membrane bound organelles that has proteins in it. they are involved in cellular process such as phagocytosis, autophagy, clearing cellular debris, cell death etc.
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). I don't know of any other organelles that are involved in this process but lysosomes do carry out a similar procedure to autophagy. It's called autolysis, and that is basically when the lysosome, excretes all of its digestive juices into the cell. It's like a self destruct and the entire cell is condemned to a digestive end. Don't worry, it only applies to damaged cells.

Autophagy primarily takes place in the cytoplasm of cells. It involves the formation of autophagosomes, which are double-membraned vesicles that enclose cellular components targeted for degradation. These autophagosomes then fuse with lysosomes, where the breakdown of the engulfed material occurs.
Lysosomes perform many functions including autophagy , protection from foreign invaders , digestion , recycling e.t.c.
how does autophagy help in converting a tadpole larva into an adult amphibian?B ) AUTOPHAGY :By the process of autophagy lysosomes constantly remove cellular components like mitochondria etc. Cytoplasmic organelles become surrounded by smooth endoplasmic reticulum and lysosomes attach with it and discharge their contents into autophagic vacuole and the organelle is digested. Autophagy isa general; property of eukaryotic cells.C) DEVELOPMENTAL PROCESSES :Many developmental processes involve shedding or remodelling of tissues with removal of whole cells and extracellular material.It is observable in tadpole metamorphosis ( regression of tail) or in developmental processes like regression of Wolffian /Mullerian ducts

outside the cell
the lysosomes enzymes are of great importance .they digest phagocytosed food particles and also involved in the autophagy (self eating ) . they also help in extra cellular digestion . so, if these enzymes are absent then all this will stop and it can result in diseases .
This occurs during a process called autophagy. Autophagosomes encircle damaged or old organelles. they then fuse with lysosomes where these organelles are broken down and digested. This takes place in the lysosome.
Autophagy - journal - was created in 2005.
