  1. Peroxisomes, lysosomes and vacuoles Add to our cell!!!

  2. Lysosomes and vacuoles • Lysosomes are vesicles produced by the Golgi apparatus. • Lysosomes contain hydrolytic enzymes and are involved in intracellular digestion. • Digestion within the cell disposes of worn-out cell parts and is necessary for cell rejuvenation. • Vacuoles (large) and vesicles (small) are membranous sacs in the cell that store substances. • Vacuoles and vesicles can store a variety of substances for the cell. Anything from water to plant pigments and toxic substances are stored in these membranous sacs.

  3. Peroxisomes • Peroxisomes are vesicles than contain enzymes to oxidize organic substances like fats. In other words the use oxygen to break down molecules. • The enzymes in these organelles produce hydrogen peroxide • Hydrogen peroxide is broken down right away by the enzyme catalase into oxygen and water. • Peroxisomes are abundant in the liver where they produce bile salts and cholesterol and break down fats.
