Verified step by step guidance

Understand the role of the smooth endoplasmic reticulum (SER) in a cell. The SER is primarily involved in lipid synthesis, detoxification of drugs, and calcium ion storage.

Recognize that protein synthesis is not a function of the smooth endoplasmic reticulum. Instead, protein synthesis is primarily associated with the rough endoplasmic reticulum (RER), which has ribosomes on its surface.

Review the functions of the smooth endoplasmic reticulum: it synthesizes lipids, metabolizes carbohydrates, detoxifies drugs and poisons, and stores calcium ions.

Compare the functions listed in the problem with the known functions of the smooth endoplasmic reticulum to identify which one does not belong.

Conclude that protein synthesis is not a function of the smooth endoplasmic reticulum, as it is associated with the rough endoplasmic reticulum.
