LysosomesFundamental unit of life
Lysosomes
Lysosomes are cellular organelles that contain acid hydrolase enzymes that break down waste materials and cellular debris.
They can be described as the stomach of the cell.
Lysosomes are a kind of waste disposal system of the cell
Lysosomes help in cleaning the cell by digesting any foreign materials entering the cell as well as worn out cell organelles.
Foreign materials, such as bacteria and food, as well as old organelles end up in the Lysosomes, which break them into small pieces.
Lysosomes are able to do this because of the presence of hydrolytic enzymes, capable of breaking down of organic materials.
Phagocytosis : Lysosomes digesting food
Lysosomes contain active
hydrolytic enzymes
The hydrolyticEnzymes digest the
food
Lysosomes fuses with
food vacuole
Autophagy : Lysosomes breaking down damaged organelle
Lysosomes contain active
hydrolytic enzymes
The hydrolyticEnzymes
digest damaged organelle
Lysosomes fuses with
vesicle containing damaged organelle
During the disturbance in cellular metabolism for example, when the cell gets damaged Lysosomes may burst and the enzymes digest their own cell.
Therefore Lysosomes are also called suicide bags
Lysosomes : SUICIDE BAGS
Peroxisomes are microsbodies. They are bound by a single membrane and contain enzymes that produce hydrogen peroxide as a by-product.
Peroxisomes contain enzymes that work by transferring hydrogen from a substrate to oxygen, thereby producing hydrogen peroxide as a by-product. Hydrogen peroxide is toxic to the cell, but peroxisomes also contain an enzyme that is capable of converting hydrogen peroxide to water.
Peroxisomes
Peroxisomes work in a very specific way. Their enzymes attack complex molecules and break them down into smaller molecules.
One of the byproducts of the digestion is hydrogen peroxide (H2O2). Peroxisomes have developed to a point where they are able to contain that hydrogen peroxide and break it down into water (H2O) and oxygen (O2).
The water is harmless to the cell and the oxygen can be used in the next digestive reaction.
Creating Hydrogen Peroxide
H₂O₂ + H₂O = 2H₂O + O₂
