What is the function of Lysosome?

Question

please tell me!

Answer 1

The main fuction is acid hydrolysis.

Answer 2

Intracellular digestion. They contain hydrolytic enzymes like proteases, amylases etc. The material that is to be digested come closer to the lysosome & lysosome takes it inside it for digestion.

They are also called as suicidal bags since they destroy cell if it is damaged.

Answer 3

The lysosome is basically the cell's cleaning crew, as the other posters indicated. If you need a good way to remember it's function, just think of lysol. It has the same beginning as lysosome and it has the same function :)

Answer 4

Lysosome = break down food into smaller particle or molecule, so the other cells may use and to destroy old cells.

Hope it may help,

thanks.

Answer 5

They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria.

--------------------------------------...

Lysosomes are the cells' garbage disposal system. They degrade the products of injestion, such as the bacterium that has been taken in by phagocytosis seen in the above cartoon. After the bacterium is enclosed in a vacuole, vesicles containing lysosomal enzymes (sometimes called primary lysosomes) fuse with it. The pH becomes more acidic and this activates the enzymes. The vacuole thus becomes a secondary lysosome and degrades the bacterium.

Lysosomes also degrade worn out organelles such as mitochondria. In this cartoon, a section of rough endoplasmic reticulum wraps itself around a mitochondrion and forms a vacuole. Then, vesicles carrying lysosomal enzymes fuse with the vesicle and the vacuole becomes an active secondary lysosome.

A third function for lysosomes is to handle the products of receptor-mediated endocytosis such as the receptor, ligand and associated membrane. In this case, the early coalescence of vesicles bringing in the receptor and ligand produces an endosome. Then, the introduction of lysosomal enzymes and the lower pH causes release, and degradation of the contents. This can be used for recycling of the receptor and other membrane components.
