👉 Autophagy, also known as lysosomal degradation or endoplasmic reticulum degradation, is a process in which cells break down damaged organelles and their contents through the process of autophagia. This process involves the engulfment (autophagia) and digestion (lysosome) of cellular components, such as proteins, lipids, and nucleotides. The autophagic process occurs in both eukaryotic cells and prokaryotes, but it
