Final answer:
The smooth endoplasmic reticulum (SER) is responsible for the synthesis of steroid hormones, among other functions including lipid and carbohydrate synthesis and detoxification.
Step-by-step explanation:
Yes, the smooth endoplasmic reticulum (SER) does create steroids. The SER is involved in several crucial cellular functions, including the synthesis of carbohydrates, lipids, phospholipids, and steroid hormones, as well as the detoxification of medications and poisons. It has a smooth appearance because it lacks ribosomes on its surface, unlike the rough endoplasmic reticulum (RER). In particular, cells that are responsible for the production of a large number of lipids, such as Leydig cells in mammalian testes, have an abundant amount of SER to facilitate the production of steroid hormones like testosterone.
