Cells in the pancreas are responsible for producing insulin, a protein excreted from the cell and used to help regulate blood sugar levels. Since the protein will be released out of the cell in which it is made, which of the cell's ribosomes are most likely involved in its production?
What will be an ideal response?
The ribosomes on the endoplasmic reticulum will make it so it can be wrapped in membrane and sent to the Golgi apparatus.
