Protein degradation is compartmentalized either in macromolecular structures known as ____ or in degradative organelles such as ____.
A) ribosomes; endoplasmic reticulum
B) ribosomes; Golgi
C) proteosomes; mitochondria
D) proteasomes; lysosomes
E) lysosomes; endoplasmic reticulum

Question

Quizplus · Accepted Answer

Protein degradation is compartmentalized in proteasomes, which are macromolecular structures, and in degradative organelles such as lysosomes. Therefore, the correct answer is D (proteasomes; lysosomes). The other options are incorrect because ribosomes and Golgi are not involved in protein degradation, and the endoplasmic reticulum and mitochondria are not primarily degradative organelles.
