Quizplus · Accepted Answer

The smooth ER is primarily involved in detoxification and drug metabolism, due to the abundance of enzymes such as cytochrome P450 in its membrane. Therefore, option B is the correct choice. The rough ER is involved in protein synthesis and processing, the Golgi apparatus is involved in protein modification and sorting, the nuclear envelope is a double membrane that surrounds the nucleus, and transport vesicles are responsible for moving molecules within the cell.
