Question

8 multiple choice 1 point what is the primary function of the smooth endoplasmic reticulum? protein synthesis dna replication lipid synthesis and detoxification ribosome production

Explanation:

The smooth endoplasmic reticulum lacks ribosomes, so it does not perform protein synthesis (a function of the rough ER with ribosomes). DNA replication occurs in the nucleus, and ribosome production is handled by the nucleolus. Its key roles include lipid synthesis (e.g., phospholipids for cell membranes) and detoxification of drugs/toxins in cells like liver cells.

Answer:

Lipid synthesis and detoxification
