17. The makes up more than half the total membrane system in many endoplasmic reticulum (ER) eukaryotic cells. Use this sketch to explain the and the difference lumen, transport vesicles, between and smooth rough ER. 18. List and describe three major functions of the smooth ER. 19. Why does alcohol abuse increase tolerance to other drugs such as barbiturates? 20. The rough ER is studded with ribosomes. As proteins are synthesized, they are threaded into the lumen of the rough ER. Some of these proteins have carbohydrates attached to them in the ER to form What does the ER then do with these secretory proteins? glycoproteins. 21. The transport vesicles formed from the rough ER fuse with the Golgi apparatus. Use this sketch to label the and faces. Describe what happens to a transport cis trans vesicle and its contents when it arrives at the Golgi.
