View the animation below, then complete the quiz to test your knowledge of the concept.






1The sequence for the processing of proteins produced within the cell is...
A)Proteins are broken into fragments, transported to the rough endoplasmic reticulum, fuse with a Golgi vesicle containing class II MHCs, and this complex is transported to the plasma membrane.
B)Proteins are broken into fragments within a vesicle, which fuses with a Golgi vesicle containing class I MHCs, and this complex is transported to the plasma membrane.
C)Proteins are broken into fragments within a vesicle, which fuses with a Golgi vesicle containing class II MHCs, and this complex is transported to the plasma membrane.
D)Proteins are broken into fragments, transported to the rough endoplasmic reticulum, combined with class II MHCs, move to the Golgi apparatus, then to the plasma membrane.
E)Proteins are broken into fragments, transported to the rough endoplasmic reticulum, combined with class I MHCs, move to the Golgi apparatus, then to the plasma membrane.



2The sequence for the processing of proteins originating outside of the cell is...

B)Proteins are broken into fragments within a vesicle, which fuses with a Golgi vesicle containing class I MHCs, and this complex is transported to the plasma membrane.
C)Proteins are broken into fragments within a vesicle, which fuses with a Golgi vesicle containing class II MHCs, and this complex is transported to the plasma membrane.
D)Proteins are broken into fragments, transported to the rough endoplasmic reticulum, combined with class II MHCs, move to the Golgi apparatus, then to the plasma membrane.
E)Proteins are broken into fragments, transported to the rough endoplasmic reticulum, combined with class I MHCs, move to the Golgi apparatus, then to the plasma membrane.



3Foreign antigens presented on class I MHC molecules...
A)stimulate other immune system cells to respond to the antigen.
B)stimulate macrophages to respond to the antigen.
C)stimulate cell destruction by macrophages.
D)stimulate cell destruction by activated T-cells.
E)are not recognized by the T-cells and do not stimulate cell destruction.



4Fragments of foreign proteins are antibodies.
A)True
B)False



5Viruses and self-proteins are examples of proteins produced inside of the cell.
A)True
B)False
