Question

Quizplus · Accepted Answer

The smooth endoplasmic reticulum (ER) is mostly devoid of ribosomes and is involved in lipid metabolism, steroid hormone synthesis, and detoxification of drugs and toxins. Ribosomes are present on the rough ER, which is involved in protein synthesis and trafficking. When cells are producing large quantities of lipid, the smooth ER becomes more prominent and actively involved in lipid metabolism, making ribosomes less necessary in this process.
