NO
Key Concept
Ubiquitin-proteasome and lysosomal degradation pathways
Explanation
Cytosolic proteins are primarily degraded by the ubiquitin-proteasome system, while lysosomal compartments are involved in autophagy, which can also play a role in degrading intracellular pathogens. The classical presentation pathway refers to the presentation of antigens on MHC class I molecules, which is not directly related to the degradation of cytosolic proteins or lysosomal contents.
