Precursors to S·R·E·B·P·s are found on this structure, where they are bound to S·C·A·P. Stress in this structure causes cleavage of A·T·F·6. This structure produces membrane (10[1])lipids such as phospha·tidyl·choline (10[1])and is responsible for the synthesis of cholesterol. (10[3]-5[1])Stress in this structure (10[1]-5[1])induces (10[1])U·P·R, (10[1]-5[1])which degrades (10[1])misfolded proteins. This structure (10[1]-5[1])stores calcium ions, (10[12])and (-5[1])is the origin (10[2])of vesicles (10[4])that transport (10[3])proteins (10[1]-5[3])to the Golgi (10[2])body. (10[7]-5[2])One subtype of this structure (10[1])contains (10[1])ribosomes (10[3])embedded (10[2])into its surface. (10[9])For (10[1])10 points, (10[2])name this organelle that surrounds the nucleus, divided into smooth and rough types. (10[1])■END■ (10[4])
