Question

select the part whose main job is to help ribosomes make proteins. rough endoplasmic reticulum centrosome golgi lysosome

Explanation:

The rough endoplasmic reticulum (RER) has ribosomes attached to its surface. These ribosomes synthesize proteins, and the RER helps in the proper folding and initial processing of these newly - made proteins. The centrosome is involved in cell division (organizing microtubules). The Golgi apparatus modifies, sorts, and packages proteins (but not in the initial process of helping ribosomes make them). Lysosomes are involved in digestion and waste removal.
