Question

Read these instructions carefully or you will lose a painful number of points on this one. For the different intracellular localizations associated with proteins listed on the LEFT, Choose one mode of translation (A, B, or C), AND one path of trafficking (1-6) associated with the best answers among the descriptions listed on the RIGHT: (Note, each protein location will have one mode of translation and one path of trafficking, any answers may be used more than once, and not all paths of trafficking will be used)

Explanation / Answer

Cytosolic protein - on free ribosome , stays in cytosol and perform job there. plasma membrane protein - synthesis by ribosome into ER membrane, trafficking vesicles ( plasma membrane) Mitochondrial matrix protein - on free ribosome , stays in cytosol. Nucleoplasm - on free ribosome , bound by nuclear import receptor and transported Nucleus - on free ribosome , bound to nuclear importer and transported Exported from cell - ( they are secretory proteins) ribosomes on ER lumen ,trafficking vesicles ( golgi)
