GinnyAnswer

Final answer:

Ribosomes on the rough endoplasmic reticulum (RER) are responsible for protein synthesis and membrane production.


Explanation:

Ribosomes, which are particles that contain RNA and proteins, synthesize proteins. The rough endoplasmic reticulum (RER) has ribosomes along its surface, and the proteins they create are either secreted or incorporated into membranes in the cell. Rough ER is vital for protein synthesis and membrane production.
