Quizplus · Accepted Answer

The smooth endoplasmic reticulum (SER) is primarily involved in detoxification of drugs and poisons in liver cells. This is because the SER contains enzymes called cytochrome P450s that can modify and break down many foreign substances. Rough endoplasmic reticulum (RER) is involved in protein synthesis, the Golgi apparatus processes and packages proteins, the nuclear envelope encloses the nucleus, and transport vesicles move molecules between different parts of the cell.
