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

• 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.

• Lysosomes are found all around the cell but mostly by the cell wall and the Golgi Apparatus

I love my birthplace the Golgi apparatus

Page 4: I am a Suicide Bag

• 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

• 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 AcidLysosome is breaking down the Mitochondria

• 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

Thank for listening to a suicide Bag, it makes me feel important
