Composed of membranous tubules and sacs known as cisternae, the two types of this structure are differentiated by the presence of ribosomes.
An enzyme located in this structure in liver cells is responsible for the removal of the phosphate group from the first byproduct of glycogen hydrolysis. Barbiturates and alcohol induce proliferation of these structures, which play an additional role in detoxification. In the ovaries and testes, this structure is responsible for production of sex hormones. Composed of membranous tubules and sacs known as cisternae, the two types of this structure are differentiated by the presence of ribosomes. For 10 points, name this system of intracellular membranes that comes in "rough" and "smooth" varieties.
