Question

disscuss the lysosomes and peroxisomes

Answer 1

•Lysosomes=> Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.



•peroxisomes=> Peroxisomes are small, living, membrane bound, sac like cell organelle found in photosynthetically active cells of plants, liver and kidneys. These are meant for removing toxic substances from the cell by oxidative reactions. These are also involved in photorespiration in plants.

Peroxisomes are about the size of lysosomes (0.5–1.5 µm) and like them are enclosed by a single membrane. They also resemble lysosomes in being filled with enzymes. In humans, new peroxisomes are formed by the fusion of vesicles released by the endoplasmic reticulum with vesicles released by mitochondria.
