Question

Quizplus · Accepted Answer

Protein degradation is compartmentalized in proteasomes and lysosomes. Proteasomes are responsible for degrading unneeded or misfolded proteins in the cytoplasm, while lysosomes are responsible for degrading extracellular material taken up by the cell, as well as intracellular material like organelles or proteins that have been targeted for degradation.
