Solution
The processes that involve movement of protein cargo without unfolding the protein are:
-
Exocytosis by vesicles: This process involves the movement of molecules out of the cell via vesicles. The protein cargo does not need to be unfolded for this process.
-
Endocytosis by vesicles: This is the process by which cells internalize molecules (including proteins) from the extracellular environment. Again, the protein cargo does not need to be unfolded for this process.
-
Nuclear transport: This process involves the movement of molecules, including proteins, into and out of the nucleus. The proteins do not need to be unfolded for this process.
On the other hand, translocation into the chloroplast and translocation into the mitochondria usually require the protein to be unfolded before they can be imported.
