In muscles, calcium is stored in this organelle, and in the adrenal cortex this organelle synthesizes steroids.
In muscles, calcium is stored in this organelle, and in the adrenal cortex this organelle synthesizes steroids. ERAD is a process in which misfolded proteins are degraded in these structures, where they are usually folded with the help of chaperones.  One type of this organelle forms transport vescicles to the (*) golgi apparatus and is prominant in hepatocytes, while the site of mRNA translation, ribosomes, occur in another.  For 10 points, name this system of membrane enclosed tubes and sacs that synthesizes proteins and lipids and comes in smooth and rough varieties.
