1 | The 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. |
|
2 | The sequence for the processing of proteins originating outside of 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. |
|
3 | Foreign 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. |
|
4 | Fragments of foreign proteins are antibodies. |
| A) | True |
| B) | False |
|
5 | Viruses and self-proteins are examples of proteins produced inside of the cell. |
| A) | True |
| B) | False |
