Lysosome By Eddie Hurtig, Carrie Rush, Natalie Howard
General Info Lysosome in Greek means “breakdown body” The lysosome is an organelle that digests food and waste for the cell. Lysosomes in animal cells but are not in most plant cells.
How It’s Made The enzymes are put together in the rough Endoplasmic Reticulum and are then transported to the Golgi Apparatus in a transport vesicle. Endoplasmic ReticulumGolgi Apparatus The Golgi Apparatus refines the enzymes within the membrane of the Lysosome so that they can be effective. Golgi Apparatus
Structure Is made up of enzymes contained within a lipid bilayer membrane lipid bilayer membrane These Enzymes are hydrolytic. Which basically means that they digest stuff.
What It Does Digests food particles and sends them to be used Destroys harmful bacteria Recycles damaged and old organelles Cleans the cell of unwanted “crap”
How it digests It digests organelles by engulfing them in the lysosome and exposing them to the digestive enzymes (Oh Fun!) Once the lysosomal enzymes have digested the food particles, the digested food diffuses through the membrane and into the cell to be used by the cell for energy or growth. lysosomes digest food and bacteria by fusing with the vacuoles exposes the molecules to the hydrolyzing enzymes of the vaculole
Enzymes Major Enzymes in the Lysosomes Protease Hydrolyzes (digests) proteins Lipase Hydrolyzes fats into fatty acids and monogycerides Nucleases Hydrolyze nucleic acids (DNA or RNA) into nucleotides Amylase Digests starches into sugars Lipase Hydrolyzes lipids Source:
Why They’re Important White blood cells in the human body can digest bacteria in their lysosomes (textbook p. 61) This is a key roll that helps prevent Disease from spreading throughout the body Lysosomes are also very important in the development of Embryos
