Final answer:
Liver cells are most likely to have the greatest concentration of smooth endoplasmic reticulum due to their significant involvement in detoxification. The correct answer is option b).
Step-by-step explanation:
The most likely cell type to have the greatest concentration of smooth endoplasmic reticulum (SER) would be a cell that is heavily involved in the synthesis of lipids, phospholipids, and steroid hormones, as well as the detoxification of medications and poisons.
Looking at the provided options, the liver cells are a prime candidate because the liver is an organ responsible for detoxification and metabolism of various substances, which are key functions of the SER. Additionally, muscle cells possess a specialized form of SER known as the sarcoplasmic reticulum, which stores calcium ions necessary for muscle contractions.
However, they are not primarily known for lipid and steroid hormone synthesis, unlike liver cells or other cells that specialize in hormone production. In summary, while other cells also contain SER, liver cells would have the greatest concentration due to their extensive involvement in detoxification, carbohydrate metabolism, and the synthesis of certain lipids.
