Macromolecule Hydrolysis

Post by larock01 » Sat Apr 15, 2006 7:35 pm

Which organelle is the site of macromolecule hydrolysis in the cell?

I am hesitating on either:
- Mitrochondria
- Centrosome
- Lysosome
- Golgi Apparatus
- Peroxisome

Hopefully my research up to this point his been effective and the answer is one of those.

Thanks in advance

The correct answer is the third option (lysosome). Lysosomes contain hydrolytic enzymes (or hydrolases) which catalyse the digestion of many substances in the cell. Some examples of hydrolytic enzymes are:

- Phosphatases: They take part in the hydrolysis of phosphates of organic molecules.
- Lipases and phospholipases: They take part in the hydrolysis of lipids and phospholipids.
- Glycosidases: They take part in the hydrolysis of polysaccharydes.
- Catepsins and other proteases: They take part in the hydrolysis of proteins.
- Nucleases: They take part in the hydrolysis of nucleic acids.
