Final answer:
The proteasome system and lysosomal system contribute to the immunological function of degradation and elimination of pathogens.
Step-by-step explanation:
The proteasome system and lysosomal system contribute to the immunological function of degradation and elimination of pathogens in the body.
Lysosomes are organelles that contain hydrolytic enzymes, which are used to destroy pathogens that enter the cell through a process called phagocytosis or endocytosis.
The proteasome system, on the other hand, is responsible for the degradation of intracellular proteins, including those involved in immune responses.
