proteasome

Ubiquitin tagging allows the 19S subunit of the 26S proteasome to recognize the potential protein substrate.

Proteasomes are protein complexes. These protein complexes are present in eukaryotes, some bacteria and in archaea. The proteasomes are located in the nucleus and the cytoplasm when looking at eukaryotes.

The two types of lysosomes are Peroxisomes which is a vesicle containing oxidases and catalase. It's located by the smooth ER of the animal cell. The second type of lysosme is the Proteasome which is a tiny barrel-shaped structure that contain proteases. Peroxisomes functions include oxidizing amio acids and fatty acids; also detoxifing alcohol. The functions of Proteasome includes degrading unneeded, damaged, or faulty proteins by cutting them into small peptides.

The function for the lysosomes is to get rid of all the waste in a cell. An analogy might be a garbage man or garbage truck. Another analogy for the lysosome is our digestive system because it helps take out the junk in our body and so does the lysosome for the cell. It might also functions sort of like a garbage disposal, since it breaks down waste.
