RPN1 and RPN2 code for an integral protein within this structure. One type of this structure contains glucose-6-phosphatase and stores and pumps calcium ions. Vesicles coated with COP I are targeted to return to this organelle, while those with COP II leave it. One type metabolizes glycogen and synthesizes steroids, while another type synthesizes secreted proteins. Its lumen is contiguous with the
RPN1 and RPN2 code for an integral protein within this structure. One type of this structure contains glucose-6-phosphatase and stores and pumps calcium ions. Vesicles coated with COP I are targeted to return to this organelle, while those with COP II leave it. One type metabolizes glycogen and synthesizes steroids, while another type synthesizes secreted proteins. Its lumen is contiguous with the perinuclear space, and the two different types of this organelle synthesize lipids and proteins. For 10 points, name this organelle in which the presence of bound ribosomes differentiates the "rough" and "smooth" types.
