Where exactly in the cell are polypeptides made?

In protoplasm. on ribosome associated with Endoplsmic reticulum.

Protein synthesis takes place here.(translation)

Polypeptides are made of many peptides!
In cell, polypeptides are often modified in Golgi by attaching oligosaccharides.
When polypeptides emerge from polyribosomes, they often are caught by chaperonins which help polypeptides fold into their tertiary structure. These folded polypeptides can unite one with other to form a multi-polypeptide structure. This is called tertiary structure of polypeptides.

Good luck!
