The smooth endoplasmic reticulum is studded with ribosomes that synthesize polypeptides, whereas the rough endoplasmic reticulum lacks ribosomes and specializes in lipid synthesis and detoxification.
Answer: Answer
Answer
False. The statement reverses the structural characteristics and primary functions of the rough and smooth endoplasmic reticulum.
The statement is false because it swaps the structural definitions and cellular functions of the two types of endoplasmic reticulum. In eukaryotic cells, the rough endoplasmic reticulum is named for the ribosomes attached to its cytoplasmic surface, which synthesize proteins destined for membranes or secretion. In contrast, the smooth endoplasmic reticulum is tubular, lacks ribosomes, and primarily synthesizes lipids, phospholipids, and steroid hormones while detoxifying metabolic byproducts and drugs.
