Question

check point identify does the rough er or the smooth er send proteins on to the golgi apparatus?

Explanation:

The rough endoplasmic reticulum (ER) is studded with ribosomes which synthesize proteins. These proteins are then transported to the Golgi apparatus for further modification and sorting. The smooth ER is mainly involved in lipid synthesis and detoxification, not protein - transport in the same way as the rough ER.

Answer:

The rough ER sends proteins on to the Golgi apparatus.
