Final answer:
The correct answer to this question is thus (b) Rough endoplasmic reticulum.
In a pancreatic cell responsible for producing digestive enzymes, an elaborate rough endoplasmic reticulum would be expected due to its role in protein synthesis and modification, which are crucial for enzyme production.
Step-by-step explanation:
In a pancreatic cell producing digestive enzymes, we would expect to find an elaborate rough endoplasmic reticulum (RER). The rough endoplasmic reticulum is studded with ribosomes and is the site of protein synthesis and modification, which is crucial for producing enzymes. These enzymes, such as pancreatic amylase, trypsin, and pancreatic nuclease, are part of the pancreas's role in the digestive system.
Notably, Figure 3.14 Endoplasmic Reticulum (ER) from the referenced material shows the ER's winding network, with the rough ER having numerous ribosomes on its surface.
Moreover, pancreatic acinar cells, illustrated in Figure 3.12 and Figure 4.19 from the provided references, show secretory vesicles containing enzymes ready for export via exocytosis, further emphasizing the significance of the RER in these cells. In contrast, smooth endoplasmic reticulum, which synthesizes lipids and engages in detoxification, would not be as prominent in pancreatic cells focused on enzyme production. The correct answer to this question is thus (b) Rough endoplasmic reticulum.
