What are some examples of human cells that produce proteins for exportation? Which cytoplasmic organelle is expected to be well- developed and abundant in those cells?
Specialized cells of the glands, like the Langerhans cells of the pancreas (that produce insulin) or the saliva-producing cells, are examples of secretory cells. In cells specialized in secretion, the endoplasmic reticulum and the Golgi apparatus are well-developed since they participate in the storage and processing of proteins for exportation.
