Final answer:
Pancreatic cells have an abundance of rough ER to meet the protein production demands of the cell.
Step-by-step explanation:
Pancreatic cells have an abundance of rough ER to meet the protein production demands of the cell. Rough endoplasmic reticulum (RER) is studded with ribosomes, which are sites of protein synthesis. The primary job of the rough ER is the synthesis and modification of proteins, which are destined for the cell membrane or for export from the cell.
