Chapter 4: A Tour of the Cell 5. Smooth endoplasmic reticulum (SER) lacks _, which gives it a "smooth" appearance. 6. True or false: If false, make it a correct statement. The smooth endoplasmic reticulum con- tains many enzymes that allow it perform functions like detoxify circulating drugs. 7. Use Figures 4.14 (page 65 of your textbook) and 4.17 (page 67 of your textbook) to answer the following question. Place the following steps in the order in which they occur...
