Beta cells in the pancreas produce and secrete the protein hormone insulin. You would expect to see a relatively large amount of which organelles in these cells?

Question

Quizplus · Accepted Answer

Beta cells in the pancreas produce and secrete insulin, which is a protein hormone. Protein synthesis occurs in the rough endoplasmic reticulum (ER), and the Golgi apparatus modifies, sorts, and packages proteins for secretion. Therefore, we would expect to see a relatively large amount of rough ER and Golgi apparatus in beta cells. Mitochondria are important for energy production and cilia are involved in movement, neither of which are directly related to the production of insulin. Smooth ER and lysosomes have different functions than the ones required for protein synthesis and secretion. Cytoskeleton and peroxisomes also do not play direct roles in protein hormone synthesis and secretion.
