Mechanism associated with protein folding

[Jonooo]

I've read my textbook, and search online but can find no information in regards to this question. Perhaps you could help.

Their is a mechanism associated with protein folding that is found in human cells but not found in bacterial cells. I need to know what it is.

As far as I'm aware, their is several organelles in Human Cells, but only Ribosome's in Bacterial Cells which are Prokaryotes. Is this correct? If true, has the first question got anything to do with the fact that Human Cells have cell membranes and so, prevents protein becoming stuck in the walls of the cell?

Any help much appreciated!

ribosomes are not the only organelles in prokaryotes, but yes, prokaryotes do not have membrane-enveloped organelles So yes, it could have to do something with the membranes. Maybe something with the localization (e.g. SRP and SRPR?). Do prokaryotes have chaperones or chaperonines?
