I am a Suicide Bag

1. I am a Suicide Bag

2. Lysosomes break down cellular waste products, fats, carbohydrates, proteins, and other macromolecules into simple compounds, which are then returned to the cytoplasm as new cell-building materials. I eat waste

3. Lysosomes are mostly budded off the Golgi apparatus membrane. • Sometimes lysosomes come from late endosomes, which are vesicles that carry stuff into the cell in a process known as endocytosis. I love my birthplace the Golgi apparatus • Lysosomes are found all around the cell but mostly by the cell wall and the Golgi Apparatus

4. Lysosomes are used for the digestion of macromolecules from dying cells or larger extracellular material, like foreign invading microbes endocytosis and autophagy. • Autophagy may also lead to, a form of programmed self-destruction, or autolysis, of the cell, which means that the cell is digesting itself. • Other functions include digesting foreign bacteria (or other forms of waste) that invade a cell and • helping repair damage to the plasma membrane by serving as a membrane patch, sealing the wound. • In the past, lysosomes were thought to kill cells that were no longer wanted, such as those in the tails of tadpoles or in the web from the fingers of a 3- to 6-month-old fetus. • While lysosomes digest some materials in this process, it is actually accomplished through programmed cell death, called apoptosis. I like destroying my home and patching holes

5. Lysosome Structure • Like other microbodies, lysosomes are spherical organelles contained by a single layer membrane, though their size and shape varies to some extent. • This membrane protects the rest of the cell from the digestive enzymes contained in the lysosomes, which would otherwise cause significant damage. • The cell is further safeguarded from exposure to the biochemical catalysts present in lysosomes by their dependency on an acidic environment. I love living in Acid Lysosome is breaking down the Mitochondria

6. Interesting Lysosome Facts • The lysosome contains over 40 enzymes, some of which are the proteases, nucleases, and phopholipases. • These enzymes optimally work at a pH of 5 (acidic), so should these enzymes leak out they would cause minimal damage to the cytoplasm • Word origin: from the Greek words lysis, which means dissolution or destruction, and soma, which means body. I look pretty cool
