Quizplus · Accepted Answer

The proteasome is the protein degradation "machine" within the cell that breaks down unwanted proteins one protein at a time. The lysosome and peroxisome are organelles involved in degradation of cellular waste but not specifically for protein degradation. The ribosome is responsible for protein synthesis, not protein degradation.
